Tutorial on how to block ads in Firefox

Posted in Web by gadgetized on February 9, 2006

LogoThere are a few ways to block ads that actually work. One is AdMuncher which is great but it’s not free. The other good way that I found is through AdBlocker extension coupled with Filter.G AdBlocker Updater.
Here are the steps:
1. Install AdBlocker extension from
2. Restart Firefox.
3. Go to tools/Adblock
4. Enable Adblock
5. At the new filters type these commands:
6. Now go to and install the AdBlock Filterset.G Updater. This extension will install extra filters in your AdBlocker extension.
7. Restart Firefox.

Now you should be able to have an excellent banner/ads free experience on the web.
If you want the same benefits to work in Internet Explorer, Opera and anywhere else in the OS, then install AdMuncher (read about it here). You will have to pay 24$. That is if you have the money and blocking all ads is a MUST.

    Actually, there are free alternatives for current versions of Opera (such as Opera Ad Filter : ) or you can manually edit the .ini files as such:

    ADD TO opera6.ini (in documents and settings…. opera):

    [Adv User Prefs]
    URL Filter File=C:\_DL\filter.ini

    Then create a filter.ini:

    ; filter.ini
    ; This file is part of the Opera browser.
    prioritize excludelist=1

    Of course, this is built into Opera 9 (Tech Preview at ). You just right-click on a page that has content you want to block, then click on the items. In addition, you can setup site-specific settings for CSS, scripts and more. Built in, easily available, no extensions, no file editing.

    Sorry, but I get a little tired of the typical mentality that FireFox is automatically the best browser ever, when the much of the functionality was implemented in Opera prior.

    Opera is commonly overlooked as a contender in the browser space, and there really isn’t any good reason for it, IMO. I’m happy that more people are actually starting to use alternative browsers that do things like follow specs, but excluding other alternative browsers only hurts the movement.

    Especially now with Opera 9 having things like BitTorrent support built in, extensive customization options, gestures, full CSS 2 support (and beyond), fast-forward controls, extensability through user scripts, widgets, thumb previews of tabs, a wonderful built-in mail client, RSS reader built in, et al, there is nothing offered by other browsers (especially for a 4mb DL) that Opera can’t accomplish.

    If Firefox meets your needs perfectly, then that’s fine. Opera happens to fit mine perfectly. I appreciate evangelists as much as I participate in that arena – but do it in the spirit of enlightentment, not in the spirit of exclusion. Please don’t discount everything else without research just to fit your preferences. And I don’t mean this specifically at you – I’m using the term generically since the mentality seems to becoming disturbingly common.

    Anyway, that’s my soapbox, for what it’s worth. 🙂

    I have tried Opera and I like it very much. The only problem is that it won’t work with a lot of pages. If it did I would use it more. Thank for your comment it was very good.

    No problem – like I said, the tone may sound like a personal attack, but it wasn’t meant that way. It just seems like many proponents of the Firefox movement are becoming too narrow-minded – it used to be about how IE violated standards and had security problems, etc. Now it seems there is a lot of “FF is the light and the way, follow or be forsaken!” mentality, which I find a bit frustrating and sad.

    The main problem I’ve had with using Opera is browser descrimination. Either people are trying to hack for old versions of it, or just outright disallow it (which is actually usually defeated by using F12 > identify as IE / FireFox). Standards-wise, I had found it to generally be on-par with FF for rendering (they both have a couple of their own quirks, but pretty close to spec). However I’m not sure if they’ve changed some of this to behave more like IE now or not (due to it’s prevalence).

    Anyway, just wanted to point that out!

    If you like Opera so much and you know how to configure it, maybe you can help me. Opera runs well at home, but here at work, the fonts are messed up. They seem like they are all super squished together. I tried to change the fonts in Opera to new fonts but it did not fix my problem. Do you have any sugestions?

  5. […] Op Gadgetized staat een duidelijke toelichting op het gebruik van Adblock en de AdBlocker Filterset.G Updater. Laatstgenoemde extensie was me tot nu toe niet bekend, maar zorgt er nu wel voor dat ik onder Firefox nog schonere pagina’s te zien krijg dan voorheen. […]

    You mean in the rendering of web pages? Well, it’s not an issue I’ve every run across personally, though there are a few things that come to mind as possible culprits:

    + Do you have more than 1024 fonts installed? If so, then Opera 9 has a fix (check the bottom of the change log, windows specific fixes : ).
    + In font settings (Preferences > Advanced) for webpage normal font check the minimum font size and the size of the font itself.
    + Do you have a ton of fonts installed on your system? Some of them could have problems and be interfering. There is a tool called fifofo that can resolve system font problems ( DL:, info : ).
    + Do you have Adobe Type Manager installed? It is known to currently cause some interference.
    + Do you have any user.js files that could be modifying things?

    Again, I’ve never personally had the problem, so I’m not sure – but those are some items that I’m aware of as possible culprits. If all else fails you could try the Opera forums – they’re generally pretty responsive.

    Hope that helps… 🙂

    You can also use it to block traffic scripts that slow down the page loading time.
