[Windows] Find and delete dead or duplicate bookmarks/favorites with AM-DeadLink

2013-03-25_190442Bookmarks (or favorites, as they are known in Internet Explorer) are very useful in helping keep track of websites we want to revisit in the future, for one reason or another. The issue with bookmarks is often people have so many bookmarks, it is hard to manage them all. So a program that gets rid of dead bookmarks (bookmarks for websites or pages that no longer work) and gets rid of duplicate bookmarks (multiple bookmarks of the same page) is an essential tool to have. AM-DeadLink is one such tool.


Main Functionality

AM-DeadLink identifies dead and/or duplicate bookmarks for Internet Explorer, Firefox, Chrome, and Opera, allowing you to delete them.


  • Identifies dead bookmarks
  • Identifies duplicate bookmarks
    • Note: AM-DeadLink will identify duplicate bookmarks that are of the same page and URL. Two bookmarks that are of the same website but of different pages or URLs are not considered to be duplicates.
  • Supports Internet Explorer, Firefox, Chrome, and Opera
    • Note: AM-DeadLink does not explicitly support portable versions of browsers but you can modify it to work with portable versions by going to Options -> Settings -> Bookmark files and pointing AM-DeadLink to the folder where your portable browser is.
  • Allows you to delete (or edit) dead and duplicate bookmarks for Internet Explorer, Chrome, and Opera right from within AM-DeadLink; deleted bookmarks are then automatically saved to the respective browser once you hit the ‘Save’ button — there is no import/export required
  • Has the ability to check for dead/duplicate bookmarks stored in HTML, URL, comma-separated TXT, and tab-delimited TXT files.
    • Note: Although AM-DeadLink does not support less popular browsers, AM-DeadLink will work with less popular browsers if you use this feature of checking bookmarks stored in HTML, URL, comma-separated TXT, and tab-delimited TXT files — simply have your browser export to the supported format and use AM-DeadLink on that file.
  • Bookmarks can be opened (previewed) using AM-DeadLink’s built-in browser or you can set AM-DeadLink to open bookmarks in a regular browser instead
  • Has a built-in basic search tool
  • Can export bookmarks comma-separated or tab-delimited TXT
  • Is portable


  • Will identify dead/duplicate Firefox bookmarks, but cannot directly delete Firefox bookmarks. You either need to manually delete bookmarks from within Firefox itself or you can use a workaround (read the ‘Discussion’ section below for info on the workaround).
  • 2013-03-25_191623Portable version is not a separate download. It is one of those programs that you must select to use the portable version during installation, which I find to be annoying.


AM-DeadLink is a very easy-to-use program that allows you to delete dead or duplicate bookmarks. It works with the installed versions of Internet Explorer, Firefox, Chrome, and Opera but you can configure it to work with the portable versions of Firefox, Chrome, and Opera by pointing AM-DeadLink to the folder in which your portable browsers reside via Options -> Settings -> Bookmark files.

2013-03-25_190556The best part about AM-DeadLink is it allows you to delete dead or duplicate Internet Explorer, Chrome, and Opera bookmarks right from within the program, without any import/export required. When you run AM-DeadLink, simply select the browser who’s bookmarks you want to check and then hit the ‘Check Bookmarks’ or ‘Find duplicates’ button.

‘Check Bookmarks’ checks ten bookmarks at a time to find dead bookmarks, so if you have a lot of bookmarks it could take a few minutes to check them all. Once all bookmarks are checked, hit the ‘Sort Bookmarks with errors to the top of the list’ and all bookmarks that did not load properly are shown to you in red. To delete the bookmarks with errors, simply highlight it and right-click -> Delete or press the ‘Delete’ key on your keyboard. You can delete multiple bookmarks at once by Shift + left-clicking to highlight multiple bookmarks at once.

AM-DeadLink tells you what type of error it ran into when checking a bookmark and allows you to open bookmarks, so you can manually double-check to make sure a bookmark is actually dead before deleting it (if you want to). It is safe to delete pretty much all bookmarks that have errors except for the bookmarks that come back with “401 authentication failure” errors; a “401 authentication failure” does not necessarily mean a bookmark is dead but rather that it is a page that requires a username and password and as such AM-DeadLink was unable to access it. You probably don’t want to delete bookmarks with “401 authentication failure” errors.

‘Find duplicates’ lists for you all the duplicate bookmarks you have for the browser you are checking. Finding duplicates is instant and doesn’t take any waiting because it does not require AM-DeadLink to make connections to outside websites. Nor does finding duplicates require you to sort anything — you are simply shown all the duplicates. After (if) duplicates are found, you have the ability to delete whatever duplicates you desire in the same manner as described for dead bookmarks — highlight and right-click -> Delete or pressing the ‘Delete’ key on your keyboard.

Take note when looking for duplicates, some of the duplicates found may be duplicates but they are duplicates in different bookmark areas. For example, I have the same bookmark in Firefox’s general bookmarks and on Firefox’s bookmarks toolbar. AM-DeadLink shows them as duplicates but they are intentional duplicates (this is how I like it to be), so I don’t want to delete them. You may be in the same situation.

Be sure to hit the ‘Save’ button after deleting dead and/or duplicate bookmarks, otherwise AM-DeadLink will not save the changes in the respective browser (i.e. won’t delete the bookmarks you deleted).

The biggest drawback in AM-DeadLink is for people who use Firefox. Unfortunately for Firefox users, AM-DeadLink is able to read but not delete Firefox bookmarks. This means AM-DeadLink can and will find dead/duplicate Firefox bookmarks… but it does not allow you to delete bookmarks directly from within AM-DeadLink. Rather, once AM-DeadLink tells you which bookmarks are dead/duplicates, you need to go into Firefox’s bookmarks manager and manually delete the bookmarks from there.

Why does AM-DeadLink not allow you to delete Firefox bookmarks from within the program? The developer says it is because “this restriction is required to avoid possible conflicts with the Firefox bookmark database (or also future changes to the Firefox bookmark database)”. Whatever the reason may be, it is easy to see how this may be a deal-breaker for Firefox users — it is bloody annoying having to manually delete bookmarks from within Firefox as opposed to deleting them from within AM-DeadLink. Thankfully, there is a workaround if you use Firefox.

The workaround is exporting Firefox bookmarks to HTML, using AM-DeadLink on that HTML file, saving changes made to the HTML file, and then importing the HTML file back into Firefox. This is a bit cumbersome but it works if you use Firefox. Do take note, however, if you use this workaround then you need to make sure to delete all Firefox bookmarks from within Firefox after you export; if you don’t delete all of them from within Firefox after export, you will have duplicates when you import the HTML file later because Firefox simply imports bookmarks — it does not replace existing ones. If you go this route, be sure to create a backup of Firefox bookmarks in case something goes wrong.


The conclusion here is a no-brainier if you use Internet Explorer, Chrome, or Opera: AM-DeadLink is an excellent tool for identifying and deleting dead or duplicate bookmarks and favorites. Firefox users have a bit more difficult decision to make due to the fact that AM-DeadLink cannot directly delete Firefox bookmarks, and I’ll let Firefox users decide if they are OK with using the above-mentioned workaround or not. Overall, however, AM-DeadLink is highly recommended by dotTech.

    AM-DeadLink is old and discontinued and no longer functions as a remover of duplicate bookmarks…totally useless..

  • simon67

    DuplicateFilesDeleter helped me in this case

  • Very nice post. I jist stumbled upon your weblog and wanted to
    say that I’ve truly enjoyed surfing arolund your blog posts.
    After alll I’ll be subscribing to your rss feed and I hope you write again soon!

  • David Roper


    Mine let me sort and bring all of them together at the top, then delete all marked liked you were using a Wordprocessr, delete
    worked for me.

  • Ernie

    [@David Roper]

    How can I delete about 50 of them at one time?

  • jayesstee

    Strange!   My AM-DL v4.4 deletes OK on FF v19.0.2. Just checked and it deleted two links OK. Gues who won’t be updating any day soon?
    Maybe the FF database dates back to early versions of FF?  I don’t remember what my first version of FF was but it was about four years ago and long before the 3.6 version.

  • Ashraf

    [@jayesstee] Okay, I just checked AM-DeadLink’s change log. You are right — prior to v4.6 it could delete Firefox bookmarks. This is what the change log says: [x] Firefox: Bookmarks are now read-only and can no longer be changed or deleted within AM-DeadLink. This step was required to avoid conflicts due to changes in the Firefox database. AM-DeadLink can however still be used to open and check Firefox bookmarks for dead links.

  • Ashraf

    [@David Roper] Odd. I thought this program was always freeware. Thanks for the update!

    [@Tom] Thanks for the suggestion!

    [@jayesstee] [@jayesstee] That is odd. The Help file makes it sound like AM-DeadLink could never delete Firefox bookmarks. No, I don’t have Firefox open — the program simply won’t let me delete Firefox bookmarks, it tells me so itself.

  • jayesstee

    Further thought – FF has to be closed when using AM-DeadLink 4.4.
    Did you have FF open when you tried 4.6?

  • jayesstee

    My Comment #9 above is about just that – deleting FF bookmarks from within AM-DeadLink 4.4.   Comment #11 by David Roper confirms this!

  • Tom

    Chrome uses should consider the Bookmark Sentry extension. It does all this with ease.

  • David Roper


    I went to Softronic after a google search for 4.4 and learned that 4.4 had a Try version and a pay version (3 levels). After an author tries SHAREWARE (Try-Ware) and fails making money, he often converts it to FREEWARE to give it away.

    My attempts in the late 1980’s failed to make money, I went to programming pure Freeware.

    And I failed at that when my DOS skills could not learn VB and Windows 3 very well. My memory is still fond of FREEWARE and I will always love it.

  • Ashraf

    [@jayesstee] [@David Roper] v4.6 also has a ‘Delete’ button in the toolbar. What David/markh777 were referring to is the inability of AM-DeadLink to delete Firefox bookmarks from within the program.

    [@jayesstee] I’ll bring it back when it is fixed.

    [@David Roper] You must have downloaded the wrong thing. I don’t see why v4.4 would be tryware and v4.6 freeware. In any case, why are you downloading v4.4? It is the same as v4.6 except older.

  • David Roper

    [@David Roper]

    Okay okay…4.4 is not freeware, it’s “try ware”
    and 4.6 is Freeware.

  • David Roper

    Jayesstee , thanks. I went to Softronic and downloaded v4.4 and tried it. It allows sorting all errors to the top, then delete it with a press of RED Delete cross, bapp! it’s gone.

    Wonder why the author took it out of latest v4.6? If you DL this 4.4 version be sure to unchoose the automatic install choice and use “custom” so as not to install more than you bargained for.

  • jayesstee

    “My copy . . . . ”
    Can we have any sort of edit function back please Ashraf?

  • jayesstee

    [@markh777] [@David Roper]
    y copy of AM-Deadlink is at version 4.4 and it has a ‘delete’ button on the toolbar.
    Look for a ‘page’ icon with a red cross on it.

  • David Roper


    Yeah, you guys are world class book markers. I had only 88 to look at.

  • markh777

    [@David Roper] Lol..if you saw my BM collection…you would lol at that too…waayyy too many

  • AFPhy6

    “…issue with bookmarks is often people have so many bookmarks, it is hard to manage them all… ”

    Watch out what you’re sayin’ here, bud… I might think you were talkin’ ’bout me… with my bookmark file that is 5MegaBytes… and around 9000 entries… Ya sayin’ I might have a bit of trouble with those? Thank goodness for the “awesome bar” search ability, and that I do some sorting into subfolders.

    Actually, it is pretty amazing to me how few of mine are “dead”.

    Still, I probably ought to get this… The FF workaround is fine with me.

    However, what would REALLY be more helpful for me is some type of tool helping me (re-)sort FF Bookmarks into more (or different) sub-folders, though I don’t know when I would take the time to do that… perhaps on a trip cross-country.

  • David Roper

    Mark, just click on Bookmarks in Firefox. Find the one that’s bad or unwanted, right click on it and select Delete. Simple.

  • markh777

    Do you have a suggestion for Firefox that will remove them?

  • David Roper

    I installed it. I like the fact you can decide to make it portable if desired…or not. I ran it (using FF and Win7) and was – how do I say this professionately – It was FUN watching it check my bookmarks. It found only one. GMAIL link involved. I recommend it for anyone. Can’t hurt.

  • Gil

    Excellent program! I’ve been using AM Deadlink for years and it has made life much easier. When I run this program, usually quarterly, the program always finds some “deadlinks.” I used to try signing into the sites that AM Deadlink found as not working. AM Deadlink always found the ones that didn’t work. Nowadays, because I trust the application, I just run it, sort the results (bad to the top), and delete them. That’s how much trust I have in this program. I consider this a must-have for your bag of utilities.

  • Shawn

    Great find thanks… this will work great with my other tool that retreives links from archive.org.. time for some spring cleaning…
