SpeedyFox: speed up Firefox (seriously!)

In the past week or so SpeedyFox has been featured in articles by many popular and respected tech websites which I read (occasionally). Until now I just gave it a short glance and passed over it. I say “until now” because I finally decided to give it a go; and now I can vouch for all the other websites which wrote about SpeedyFox because SpeedyFox really does speed up Firefox.

What SpeedyFox does is actually quite elementary if you stop and think about it. You see Firefox uses SQLITE databases to store its settings and other important stuff (one database per “profile”). The longer you use Firefox, the more that database grows. SpeedyFox simply compacts that database. Smaller database = faster Firefox = happy Ashraf.

That being said, obviously the speed increase you experience after using SpeedyFox will vary depending on how long you have used the specific Firefox profile you speed up with SpeedyFox. For most of us we have never created custom Firefox profiles so we only have one profile (“default”). In that case the speed increase you experience after using SpeedyFox will depend on how long you have been using Firefox (i.e. when was the last time you formatted or uninstalled/reinstalled Firefox and deleted the settings).

Using SpeedyFox is (almost) as easy as eating pie:

  • You download SpeedyFox.
  • You close Firefox if you have it open.
  • You run SpeedyFox (no installation required):


  • You select the profile you want to speed up (most of us will only have one profile; in that case leave it at “default”).
  • You click “Speed Up My Firefox!”.
  • You wait:



The compacting of the database will depend on how large your database is. According to the developer, it can vary from 5 minutes to an hour.

  • You enjoy.

While it is hard for me to quantify in numbers the speed increase I am now enjoying, as I said the reason I am writing about SpeedyFox is because it does work.

You can download SpeedyFox from the following link:

    Just ran SpeedyFox latest up-dated version and it does work and it did speed up my FireFox. As mentioned by MR Dave, you can also compact FireFox database using CCleaner. Just check the Compact Database under FireFox and you’re done. What ever SpeedyFox does i haven’t read on yet but it does speed up your browsing a lot. Nice to know that… give it a try and try CCleaner Compact Database option and let us all know what you experience……. Does FF hog much of your resources (memory)… try Firemin, this little tool will free what ever FF hogs and it is extremely light and does what it’s meant to do. Been using it for a few months with no issues what so ever. You can get it HERE >>> http://firemin.en.lo4d.com/ You can also read this review on Cnet HERE >>> http://download.cnet.com/Firemin/3000-18512_4-75454011.html I can say that Firemin does work very well freeing up resources and it uses very little it self. You will be surprised when you us it just like i was so give it a try. I assure you that you won’t regret it…..

  • Mr.Dave

    Ccleaner can also compact the Firefox database. Look under the Cleaner tab, then Applications, then find Firefox/Mozilla (at the top of the list I see). Last option in that section is Compact Database. Check and you’re done, you can shrink the database to it’s minimum size each time you run CCleaner.

    I’ve tried CCleaner and other compactors but none gave me a significant speedup. I think I have WAY too many bookmarks!

  • Rob (Down Under)

    I have two instances of Pale Moon Portable, in two folders.
    Running well, and not interfering with FF or each other.
    I should be able to have even more folders, to give me multiple Pale Moons, which I will use for different categories of browsing. Each will retain their own open Tabs (which I do habitually)
    I have reported in more detail in Ashraf’s other page –
    [How To] Tip: Install multiple versions of Firefox to test before upgrading to latest release

  • Sir Hollingsworth II

    @Ozzie: HereHere my good man! I can’t agree with you more dear fellow. I enjoy the variety of the comments meself.

  • Jacal

    Ccleaner compacts Firefox databases.

    Pale Moon doesn’t mess with FF. All the extensions work (it is the same code).

  • Rob (Down Under)

    Can you run (have both installed) Pale Moon and FF ?
    Does Pale Moon mess with FF ?
    EG do they both recall last sessions Tabs, and they do not interfere with each other (they maintain different sets of Tabs)
    Will essential Extensions like NoScript and unMHT run in Pale Moon ?
    Are you concerned that most recent updates (particularly security ones) are not in Pale Moon (I am assuming Pale Moon does not update that often) ?

  • I’ll give Speedyfox a trial because the manual method for speeding Firefox up is a PITA. for those who Spedyfox either does not work, or want to give it a try I’ll explain the manual method though.

    #1 This is the obvious steps, included for any non-techies who read this. In Firefox Select Tools>>Options and on the box select Advanced Panel>>General Tab. If you have “Use Hardware Acceleration” selected, de-select it. Save, exit and restart Firefox if not go to the next step.

    If you added any new Extensions or Add-ons before this happened, try disabling them to see if that helps, or updating them. You might try disabling them all and then re-enabling them one at a time to see if one of them is the problem. If that doesn’t help proceed to step #2

    #2 This will clear your browsing history and your record of open tabs so back them up first if that’s a consideration. Next thing to try go to Help>>Troubleshooting Information and a troubleshooting information tab will open. Under the Application Basics section, click on Open Containing Folder. A window with your profile files will open. There are alternate ways to find this folder but it varies by OS and version of the OS. Be sure to exit Firefox at this point so the changes you are about to make will work!

    Now this first step will delete your places database in case you have a corrupted one. That means your browsing history will be gone but your bookmarks will be OK. Find the file places.sqlite and if it exists places.sqlite-journal and rename them by adding .old to the end. The second step is to delete the old session restore files. The can slow down and hang up your browsing and cause a lot of problems. Find and delete any file named sessionstore.js, sessionstore-1.js, sessionstore-2.js, etc. in the same folder. You can close the containing folder and re-open Firefox to see if that helps. This is actually the step which Speedyfox replaces, minus deleting the sessionstore files, if it works.

    #3 If the above does NOT speed up Firefox then your problem is a corrupt profile. DO NOT DELETE your profile until you have backed up all your favorites, add-ons, etc. You will loose them. The only solution at this point is to delete your profile and create a new one.

    All this information is straight from Mozilla’s tech support database. I had to wade through it recently to help a friend who lives on the other side of the US that is having problems. I’ve elaborated on it a little for non-techies though.

    @Anyone who tried Speedyfox w/o it working. Try just deleting the sessionstore files next. Be sure to backup/bookmark your open tabs first since that’s where your browsing history is stored. That’s the second half of step #2 that Speedyfox doesn’t replace. Per Mozilla they can be a source of trouble too so it’s worth a shot.

    TIP: BleachBit (open source) does exactly what SpeedyFox does, next to cleaning my entire PC.

  • I am running the Pale Moon Browser. I installed Speedy Fox and was very surprised with just short of 20 second increase. More importantly is that my CPU is no longer running Maxed-out. Now it is mid to low.
    Even my Menus are opening more rapidly.
    What a neto’ little application.

  • Karol

    It’s me again. Reply from crystalidea.com: “SpeedyFox does not connect do any web sites, the expire dialog appeared because that version had a time limit period. Please download the latest.”

  • Karol

    I’ve launched SpeedyFox today and window appeared with the information: “This version of the program is expired. You will be refirected (original spelling) to our web site now.” I’m interested how SpeedyFox did connect to his web site (SpeedyFox never asked my firewall for internet connection) and found out that the present version was out-of-date. Has Crystalidea (thanks to SpeedyFox) a possibility for spying people?

  • dagasque

    @gates13: I’ve got the latest version of Firefox for Windows and it runs fine for me.

  • dagasque

    As a previous comment, it took about five seconds to compact my FF database too. I opened six FF tabs of varying page sizes- all opened in about ten seconds. Prior to this, it took about thirty to forty seconds for the same to load, so yeah…about a three to four hundred percent increase. Could be one of the better d/l’s I’ve run across in the past few months, indeed. Thanks!

  • Kraal FictionWriter

    @Jyo: Thanks for the advice.

    Well, I ran it and….it took maybe 5 seconds. I’m not sure it did anything. Does that mean that my profile was already small anyway? Which sounds funny, because I’ve used Firefox for a long time…

    All well. Like Jyo said, it didn’t hurt. Even if it didn’t do anything. I’ll hang on to the tool, because maybe it’ll work someday.

    Gates13: I have also used it on Firefox 3.5.3. While it did nothing, it gave me no issues or complaint about the version. I run Firefox in Vista x64.

  • Ashraf

    @gates13: It works just fine on the latest Firefox >.>’. What version are you using? I am running v3.5.3 and it works just fine.

  • gates13

    Dear Ashraf,

    I appreciate your work, but when I tried to get this I was told it is not compatible with the latest Firefox for Windows.

    Assuming this is true, I think it should not have been featured, or else it should have been said in the first few sentences that it is not compatible with the latest Firefox. Otherwise it’s a waste of peoples time.

    THank you for your hard work.

  • Seeing as I just recently installed Windows 7 (and Firefox with it) I didn’t notice much of a difference. I’ll try it again in a few months. :P

  • MerryMarjie

    I added Speedy Fox last week and immediately noticed that Firefox opens much quicker. Granted, I haven’t observed any other changes but I’ll take those 10 to 15 seconds I was losing, LOL!

    @David Roper: I finally gave up TW RoadRunner after four years because it was slow and unreliable, had outages in my area all the time. I switched to ATT Elite and am speeding along, no blips, and I’m saving $10 each month.

  • Jyo

    @Kraal FictionWriter: yes I would recommend trying speedy fox, it didn’t really speed up my fox, but it didn’t hurt it either. the worst it could do is well…. nothing.

  • Jyo

    The “Speed Up My Firefox” process took less than 3 seconds for me, and I didn’t see much speed differences. Must be due to my lack of addons….

    note:tested on both vista home and xp home

  • Harlan

    Firefox by default checks for incompatibilities between each of your addons and your current version of FF, and it also looks for updated versions of each one. I found FF started up a lot faster on my XP/Home and XP/Pro machines when I disabled these behaviors.

  • Mary Ann TKS

    dear Ashraf, this is too good to be true! for years i just get frustrated with youtube, every second or so, buffering, buffering
    and have to wait till the solid red line ends then have to replay, what a waste of time,

    I downloaded this SpeedyFox- what do you know! I was chatting and got a link for youtube, without thinking I clicked it, oh wow! I couldn’t believe what I was hearing and seeing! Continuous play! Not even a shade of that buffering thing!! So I sent this link and they tried it immediately,(by the way, graduates of computer science) and they read your review and said “very very good” and got somewhat technical, I wouldn’t know anything about what they were really saying – ALL I KNOW IS THAT I GET TO WATCH YOU TUBE NOW! BTW, I clicked on another video-same thing, SO IT MUST BE SPEEDYFOX because that was the only thing I downloaded before clicking the youtube link.
    So, thank you for your honest reviews, and the free software with keys,,,,take care,,,,

  • Kraal FictionWriter

    You know…I have this add on called Tweak Network that says it’s supposed to speed up Firefox. Has anyone ever used /that/?

    Looking at the mixed reviews about SpeedyFox, I’m not sure I should try it. Would those who it didn’t work for recommend at least giving it a shot? (I know those who it did work for would.)

  • Ozzie

    @ DCTECHGUY: “Trying to stay on topic”? Since when did this become a space when we could not discuss alternatives? And then you go on to ask about PDFs! If you don’t like parts of the the discussion, skip over those comments. Rob has been helpful in the past, and I am happy to listen to anything he/she/both has to say.


    Trying to stay on topic: Firefox.

    Does anyone know why Firefox will not print correct PDF files when using the Adobe PDF writer?

    I have had to use IE because of my requirements to create correct PDF files from my web pages.

    Thanks to all.

  • Ozzie

    @ Rob: I definitely agree with you that FF buckles at the knees with multiple tabs open. I always have multiple tabs open as it is so convenient, and that is when FF maxes out the CPU. Still don’t know about Cometbird, though. I’ve downloaded it, but am yet to install. I might just keep the file in my downloads until the next time FF drives me round the bend and then give it a whirl.

  • Rob

    This page is interesting –

    The first post is not singing it’s praises, but I believe it dismisses fears of it being malware’ish
    However the other comments are favorable, and I agree with them when they say –
    1) It is faster
    2) it uses less memory

    I usually keep dozens of Tabs open, from session to session.
    FF buckles at the knees (or at least kneecaps my PC) more than does CometBird.

  • Ozzie

    I was just looking up Cometbird and found this on McAfee site advisor: http://www.siteadvisor.com/sites/cometbird.com/summary/

    I don’t know how old that is, but it would seem very un-Mozilla like. Also, I understand through my quick research, that unlike FF, Cometbird does not have open code (please correct me if I’m wrong). Seems to be a mixed bag of reviews. Some love it, some are indifferent saying it’s no faster or slower than FF, and some hate it because of some of its dodgy links. So I think I’ll stick with FF – even though it is causing me some grief.

  • David Roper

    Seriously if there’s any speedup then TimeWarner cable (my ISP) kills it.

    Maybe it’s the difference between 1.2 seconds speedup and 1.6 seconds speedup in a laboratory/benchmark. But I cannot tell on my laptop XP2 2GB.

    “Yeah, That’s the ticket! Blame TW.” (…spoken like Jon Lovitz)

  • Rob

    I am pretty sure it is Mozilla
    I scraped this off the CometBird’s ‘About’ box –
    Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: Gecko/20090910 Firefox/3.5.3 CometBird/3.5.3

    My version of CometBird is 3.5.3

  • Jaap

    I use Firefox on all my machines/pc’s. It’s my favorite browser. My pc’s have different operating systems: Windows XP Home; Windows XP Professional; Windows Vista Home Premium; Snow Leopard (on an iMac 20″) and Ubuntu 9.04.
    Firefox is fairly fast on all my systems, except on the XP machines. A cold start of Firefox on XP Home or XP Professional takes 20 seconds (Win XP Pro, on a one year old machine) or 40 seconds (!!) (Win XP Home, on a 5 year old machine). A warm start (starting Firefox, closing it and starting it again) takes less then 5 seconds on all the machines.
    Using Speedyfox didn’t do anything. The optimization took just one second and I noticed no difference after that. I am using Firefox now for years on that 5 year old machine, and I have used the same profile all that time. It’s onely Firefox that is slow on that machine. The other programs are as fast as they were when I bought that pc, 5 years ago.

    I also used Speedyfox on the pc of a friend and she thinks that the cold start of Firefox on her XP Home machine is a bit faster now.
    All in all, I am not very impressed by Speedyfox.

  • Ozzie

    @ J.L.: Thanks for the response. Appreciated. Actually, I tried this before, along with a number of other solutions that allegedly help the problem, but FF is still chewing up the CPU.

    @ Ashraf: No, I haven’t made any changes to FF (except for the periodic version updates). And I’m pretty sure SpeedyFox is configured correctly. The folder is the correct one, so I dunno.

    I even disabled a number of add-ons a while back, but even that didn’t do anything. When I looked into this online a little while back, I saw that many people were having problems with the browser being really slow and/or it chewing up the CPU. So at least I know I’m not alone with the problem. When it gets too slow and I’m trying to research stuff and don’t have time to sit twiddling my thumbs, I temporarily jump to IE (ugh) or Chrome (not a fan). Like I said, I just dunno why. Be nice to have a really speed Firefox though rather than the slow, old, arthritic, grey-haired fox I have at present.

    @ Rob: I’ve never heard of CometBird, but I’ll look into it. Is it a Mozilla development project?

  • Rob

    Have you guys tried CometBird ?
    It is a faster leaner version of FF.
    It uses the same add-ons.

  • @Ashraf: (-:
    Gotta love those coincidences.

  • Ashraf

    @Ozzie: Hmmm. Not sure why you aren’t seeing too big of a speed increase (if any). Did you just recently format and/or change Firefox profiles? Are you using the profile in Firefox which you used in SpeedyFox?

    @J. L.: Funny you should mention FEBE because there is an article sitting to be published on it as I type this. Just gotta wait till Locutus is done writing it.

    Also, thanks for being a great helping hand around here in terms of addressing people’s problems in comments =).

  • J. L.

    @Ozzie: I think your bad experience most likely has something to do with your profile. Try running Firefox in Safe Mode, and tick: Disable add-ons, Reset toolbars and controls, and Restore all user preference. Then Continue to Safe Mode.
    If that did work, you can narrow down the problem later, and/or create a new profile and use it from now on. FEBE, OPIE, and CLEO can help you backup/transfer your private data, add-ons, and settings.

    As for my experience in using this program, I didn’t notice much difference at all, but that is to be expected on my new Windows 7 OS.
    I did use the vacuum commands before in XP though, it worked quite effectively.

  • Ozzie

    Greetings all! I saw this recently and it caught my attention. I am a long-time user of Firefox – and I love it. However, it is starting to annoy me to the point of wanting to find an alternative because of its increasingly outrageous CPU usage and excessive load and lag times that are becoming problematic (I really, really hope Mozilla can actually fix this one day – and that that day is not too far away). So I tried Speedyfox with high hopes, as others had reported instant speed jumps, but I really can’t notice any significant difference. I’d be interested to hear other dottechies’ experiences with this prog.
