How to block advertisements in Firefox, Internet Explorer, Chrome, and Opera [2nd Edition] [Guide]

A few weeks ago we had a good discussion  regarding advertisements. There are many dotTechies who are OK with advertisements; but there are also others that are not. Out of those that dislike ads, there are some that block ads and there are some that would like to block ads but don’t know how. This article aims to change that.
Advertisements are a critical source of revenue keeping dotTech afloat (same goes for most other websites). I greatly appreciate anyone and everyone that does not block ads  on dotTech. However, I do not hold a grudge with anyone that does block ads because I understand advertisements can be very annoying (especially Flash ads ); and, I feel everyone should at least have the knowledge of how to block ads so it is by choice when (if) they decide to not block ads as opposed to by helplessness. After all, education is the key to making an informed decision. (Okay, that was a lame dialog.)
That said, this article will discuss ways on how to block ads on the four major browsers used by Windows users: Firefox, Internet Explorer, Chrome, and Opera.
Without a doubt Firefox is the easiest browser to block ads in because of its extensive add-ons support. In fact, while I don’t know if Firefox was the first browser to support adblockers, I do know Firefox is what made adblocking popular.
If you are a Firefox user and you want to block ads, look no further than AdBlock Plus . AdBlock Plus is a no-hassle, install-and-go adblocker add-on for Firefox. Really the only sort of “setup” you need to do with AdBlock Plus is select the adblocking filter you want to use:
These filters are, more or less, a definitions list telling AdBlock Plus which ads to block (similar to how there are virus definitions for anti-virus programs). You need to select one of the filters to use; unless you know what you are doing, just leave it at “EasyList” and click “Add subscription”. After the initial installation you can select to use more than one filter (“Tools” -> “AdBlock Plus Preferences…” -> “Filters” -> “Add Filter Subscription…”) but in all honesty one filter is more than enough to block 99.5% of ads. (Do note, though, if you visit non-English websites frequently, you may want to use a second non-English filter to block ads on non-English websites.)
Although AdBlock Plus blocks most ads on its own, if AdBlock Plus ever misses an ad you can right-click on the ad and select “AdBlock Plus: Block image”; this will allow you to create a custom filter blocking that ad and ads similar to it:
If AdBlock Plus misses a Flash or Java ad, a little “Block” tab will pop up above it allowing you to block it manually (since you can’t right-click on those types of ads).
Other useful features of AdBlock Plus are
I highly recommend AdBlock Plus over NoScript for ad blocking needs.
Block ads on Internet Explorer is a bit more complicated than Firefox because Internet Explore has no AdBlock Plus-like plugin. That is not to say Internet Explorer does not have adblocking plugins, but rather there is nothing for free as good as AdBlock Plus (AdBlock Pro  can be considered to be IE’s version of AdBlock Plus but AdBlock Pro costs $19.95). So, in that regard, I will provide multiple different methods on blocking ads in Internet Explorer – you decide which one is best for you. (Or, alternatively, you can switch to a real browser. =P)
Internet Explorer’s InPrivate Browsing – the mode that makes sure no browsing data is stored on your computer – has a feature that allows users to filter content. This filter can be used to block ads. A user on DSLReports forum  created an XML file out of AdBlock Plus’s list of ads to block and this XML file can be imported into InPrivate Browsing’s content filter:
The great thing about using this filter is
The thing about “InPrivate Filtering” is you must manually turn it on every time you run Internet Explorer. If you find that annoying, a simple registry hack makes “InPrivate Filtering” automatically turn on every time you run Internet Explorer. To do this registry hack
Since this method uses InPrivate Browsing’s filter, there is no need to download any plugins. The downside, however, is
Updated February 25, 2012: IE7Pro seems to have stalled in development. It was last updated in June 2010. I’d suggest looking at the Use InPrivate Browsing Filtering Capabilities method mentioned above to block ads in IE since IE7Pro is no longer being actively developed.
IE7Pro is a plugin for Internet Explorer (works on IE 6/7/8 – not just IE 7) that adds a boatload of useful features to Internet Explorer. One of the features IE7Pro adds is an adblocker. This adblocker, however, is not enabled by default after installing IE7Pro – users have to manually enable it after installation. (Be warned during the installation of IE7Pro you are prompted with – drum roll please – an ad for installing a third party program; don’t accidentally install that third party program if you don’t want it.):
After the adblocker module has been enabled, you still need to enable the Flash blocker (to block Flash ads). To do this, go to “Preferences” again, click on “Ad Blocker” and enable Flash blocker:
You have the ability to modify filters, add your own filters, and whitelist websites.
Overall I found the ad blocking features of IE7Pro to be very poor; heck it wouldn’t even block Google AdSense ads…
Update February 26, 2012: Simple Adblock now has multiple editions, Free, Pro, and Enterprise. Free is limited to blocking 200 ad requests a day. Because of this limitation, I’d suggest using the the Use InPrivate Browsing Filtering Capabilities method mentioned above to block ads in IE since Simple Adblock is no longer free.
Simple Adblock is the closest IE users will be able to get to an AdBlock Plus-like plugin. Simple Adblock uses EasyList filters (the one from AdBlock Plus) to block ads so its accuracy in blocking ads is extremely good, although not as good as AdBlock Plus since AdBlock Plus allows for usage of multiple filters. Also, while Simple Adblock does allow users to disable Simple Adblock on a specific website, there is not much users can do to block individual ads or unblock individual ads. Simple Adblock does allow users to customize the filters list, but again, that is is a hassle because users have to modify files located in Simple Adblock’s installation folder.
On the brightside, Simple Adblock is very easy to setup, requiring only two inputs from the user after installation:
After installation Simple Adblock is accessible via an icon placed in Internet Explorer’s bottom bar:
As I said, Simple Adblock is the closest free plugin Internet Explorer users will get to AdBlock Plus; a word of caution about Simple Adblock though. You should always only install plugins/add-ons/extensions from trusted sources because otherwise you could be installing a browser exploit without knowing it. Simple Adblock is not that well known (thus not fully vetted by the Internet Explorer community) and the developer does not provide any information about him/herself. I am not saying Simple Adblock is a malicious plugin (SiteAdvisor says it is clean, Download.com says it is clean, and I scanned it personally and it came out to be clean); I am saying be cautious.
Blocking ads in Chrome is just as easy as blocking ads in Firefox. AdBlock for Chrome  does what AdBlock Plus does for Firefox. In fact, AdBlock is easier to setup than AdBlock Plus; with AdBlock you do not need to select which filter’s list to subscribe to – AdBlock automatically uses AdBlock’s own filters and AdBlock Plus’ EasyList. So, to use AdBlock all you need to do is install it – it will start blocking ads instantly requiring little to no assistance from you.
Most other features present in AdBlock Plus are in AdBlock:
Unfortunately AdBlock does not have an easy way to remove false positives like AdBlock Plus does (as far as I can tell). Also, whereas AdBlock Plus fully stopped ads from being downloaded, because of the restrictions of Chrome, some ads are blocked by AdBlock after they have been downloaded as opposed to being blocked from being downloaded.
Historically, like Internet Explorer, blocking ads on Opera is a bit complicated because of Opera’s poor extendability. In the past the best way to block ads in Opera is an adblocking method  using Opera’s built in content blocker  (similar to IE’s InPrivate Filter) and an add-on  to block Flash ads specifically. However, ever since Opera introduced extensions starting in Opera 11, third-party developers have started creating add-ons for Opera. One such add-on is Opera Adblock .
Opera Adblock is an add-on for Opera that makes it extremely easy to block ads. Similar to Adblock Plus for Firefox and Adblock for Chrome, Opera Adblock utilizes ad filters to block ads, notably Fanboy and EasyList. The best part about Opera Adblock is it is extremely easy to setup and use. All you have to do is install Opera Adblock from Opera’s extensions website and you are good to go; Opera Adblock automatically starts blocking ads start installation, using Fanboy’s ad filter and CSS filter to block ads (Opera Adblock also blocks tracking websites and the annoying Facebook logins and buttons you see all over the Internet) — you don’t have to mess with any settings if you don’t want to.
If, however, you do feel inclined to customize Opera Adblock settings, from Opera Adblock’s Preferences you can…
Really the only downside I can see to Opera Adblock is that it isn’t as easy to unblock ads on specific websites as it is for Adblock Plus for Firefox or Adblock for Chrome. If you want to unblock ads on a specific website with Opera Adblock:
You need to do this for every website you want to manually unblock ads and for some websites it still may not work in which case you would have to uncheck Enable plug-ins, too.
There are multiple different ways to block ads on Firefox, Internet Explorer, Chrome, and Opera; instead of talking about all of them, I picked the best adblockers to recommend in this article. Everyone is, of course, welcome to share their opinions on which adblockers are the best (be sure to specify for which browser is the adblocker you are recommending).
Before blocking ads, always keep in mind you may be blocking the only source of revenue your favorite website has; lack of ad revenue can often times drive a website out of business, or force the website to put up a pay wall. That is not to say you are wrong or evil if you block ads (some ads, especially Flash ads, deserve to be blocked because they are so intrusive and annoying) but rather one should always consider the impact blocking ads will have on the website in question. That said, now everyone has the knowledge and tools needed to block advertisements. So, please share with us in the comments  below: Do you, or will you, block ads?
