No Block Sites Option? Why not?

User Help for Mozilla Firefox

Post Posted July 24th, 2005, 4:44 am

I've looked everywhere but I can't find an option that will allow me to block sites. I thought this would be a very basic feature. :S

Mainly because blocking sites via the browser is easy to defeat.

Parental Control - MozillaZine Forums

You can also look into HOSTS or Proxy Auto Config files, but again these are easy to defeat.

Two ways to do this ....

1st way: Firefox Security Policies, Host File or PAC File ........
2nd way: use a extension .....................
  • Rip -
    ... (Remove it Permanently) provides the ability to point at and remove permanently any item you can select. It provide a flexible and easily configurable solution to removing unwanted content from a web page. If it is just image based ad's removal you are looking for I suggest you use the rather excellent (Ad Block) extension and download a good list of regular expression for this extension (Filterset.G). ..... If on the other hand you want the power to choose what content you want removed, be it unwanted forms, text based ads or just areas of a page (or website) you don't want to see anymore, RIP is for you.
    Author's home page for this extension -
  • BlockXXX (FF 1.0.x ONLY) -
    ... scans the actual HTML document for tell-tale words and phrases. If it finds these words it disables all images and hyperlinks on the page. This design in some cases causes pictures or links to be available for a couple seconds before they are disabled. This is obviously undesirable, however the option to move to a blacklist system is even more undesirable.
    Author's home page for this extension -
  • ProCom -
    ... is a content filter for the Firefox browser, based on BlockXXX (by Tom Christensen). ProCon filters any type of web pages, but if left on default it limits itself to filter pages containing explicit content automatically, based on the text. ProCon can also censure any single word, and create a WhiteList.
    Author's home page for this extension -
  • Adblock -
    ... is a content filtering plug-in for the Mozilla and Firebird browsers. It is both more robust and more precise than the built-in image blocker. Adblock allows the user to specify filters, which remove unwanted content based on the source-address. If this sounds complicated, don't worry: it's not. Just add a few filters. Every time a webpage loads, Adblock will intercept and disable the elements matching your filters.
    Author's home page for this extension -
  • Adblock Plus -
    ... ever been annoyed by all those ads and banners on the internet that often take longer to download than everything else on the page? Install Adblock Plus now and get rid of them. Right-click on a banner and choose "Adblock" from the context menu - the banner won't be downloaded again. Or open Adblock Plus sidebar to see all elements of the page and block the banners. You can use filters with wildcards or even regular expressions to block complete banner factories.
    FYI: How is Adblock Plus related to Adblock? -
    Author's home page for this extension -
  • Adblock/Adblock Plus Filterset.G Updater -
    ... this extension automatically downloads the latest version of Filterset.G every 4-7 days. Filterset.G is an excellent set of filters that blocks most ads on the internet.
    Author's home page for this extension -
  • Flashblock -
    ... never be annoyed by a Flash animation again! Blocks Flash so it won't get in your way, but if you want to see it, just click.
    Author's home page for this extension -
  • NoScript -
    .... allows JavaScript, Java (and other plugins) only for trusted domains of your choice (e.g. your home-banking web site). This whitelist based pre-emptive blocking approach prevents exploitation of security vulnerabilities (known and even unknown!) with no loss of functionality.
    Author's home page for this extension -
  • Before installing any of these extensions .......
    READ: Problematic extensions -

later, Richard

I haven't been able to get this to install (installation is blocked, and I haven't been able to figure out what to change in the options to unblock it). Does it not work with Firefox 1.5.0.*? I couldn't find anything on the author's site that says what Firefox versions it's for.

xpinstall.enabled should be true.
You have to save the extension and install locally or add the site to the allowed sites list.
(Tools > Options > Content : "Block Popups": Allowed Sites)

Local install:
Right-click the .xpi link and choose "Save Link as.." to save the file to your harddisk (e.g. My Documents or Desktop) and then drag the file into a Firefox or Extensions Manager window or use File > Open File to install.

Thanks, Matt! That did the trick! I wonder why this about:config stuff isn't in the help files (at least under software installation)?

Dick, I tried that, and I still got the blocked installation message. Thanks, anyway!
