Firefox minimal skin, Speed-up and Norwegian Adblock list (further down)


Having a small 1024x768 display I have been looking for a browser that wastes minimal space. Internet Explorer 6 was OK,
having the possibility to stack menues, buttons and bars on one line, but then came Internet Explorer 7 :-(   (screenshots here)

So I looked at Firefox, and discovered the userChrome.css file. Here is the latest version for Firefox 57- on Windows 10:

Installation instructions are further down on the page (after the older versions). Click here to jump there!

If you are still using a Windows version with the Classic Theme you can download userChrome.css for Firefox 29-:

Now this is how you add the userChrome.css file to your Firefox

  • First, if you don't allready use Firefox, follow this link to read info and download the latest version: Firefox download
  • If you want to use the old layout with buttons, full menu and url-bar and at the top and tabs below (old style) then:
        Move all buttons/menus/fields to the "Menu bar", close the "Navigation bar" (skip this if you use the new design).
  • For Firefox 2-28: Change to small icons and make sure the "Stop" and "Reload" buttons are in that order
        ("Stop" first, to the left of "Reload)". If the buttons are not in that order they will not merge into one button.
  • Then download the right version of userChrome.css for your OS and Firefox version (look in the previous sections).
  • XP and older: Save to: c:\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Profiles\<profile-id>.default\chrome\
  • Newer Windows versions: Save to: c:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile-id>.default\chrome\
  • If the bookmarks are not showing in the sidebar (only "Unsorted Bookmarks" at the top) do as follows to expand the bookmarks:
    1: Click "Unsorted Bookmarks" (or whatever at the top line), 2: Press "up arrow" (cursor up), 3: Press "right arrow" (cursor right).

  • I have also made a search page that can search with multiple search engines. Click on the link to add MultiSearch.
  • If you want to run IE dependant code inside Firefox (without starting Internet Explorer) I recommend the IE Tab 2 extension

  • Firefox speed-up and Norwegian Adblock list

  • I have made a small compilation of speed-up tricks and ads-tracking/privacy filters for Firefox in this user.js file.
  • XP and older: Save to: c:\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Profiles\<profile-id>.default\
  • Newer Windows versions: Save to: c:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile-id>.default\
  • If you are tired of all those ads messing up pages and taking bandwidth I recommend the uBlock Origin extension.

  • If you live in Norway you might want to add some extra user-defined filters for norwegian pages to filter more ads.
        These filters can also be used in Samsung Internet Browser with AdGuard Content Blocker on Android phones.

  • Firefox build-in ads/tracking filter. Removes tracking and speeds up page loading

    First enter the URL "about:config"
    to go to Firefox advanced settings.

    A warning might appear, but just dismiss that. We know what we are doing :-)

    Enter "tracking" as the search-word.

    Right-click on the preference named "privacy.trackingprotection.enabled" and click "Toggle" to change it.

    If the preference name is not found you need to update Firefox (it should exist in the newest release version now).

    The value should change to "true".

    Close the tab to save the changes.

    To double-check you can enter the URL "about:config" again, search for "privacy.trackingprotection.enabled", and check that the value is "true".

    When a page is filtered a "shield" icon is displayed. Click on it for more info.

    If for some reason a page won't work when tracking-protection is enabled it can be disabled for that specific page by clicking on the "Options" button.

    But most pages work as normal
    Just loads much much faster!
