Mozilla Firefox is a free, open-source web browser. It has a huge range of features in the form of extensions - you can basically create your own Firefox by choosing which features you want. Most other browsers are getting extensions now, too, but Firefox still has the advantage of thousands of available extensions. Additionally, by installing Themes or using Stylish, you can change the look of Firefox to what you want.

If you want to know more, check out Mozilla's site. If you know Firefox and are interested in my scripts for Greasemonkey or my styles for Stylish, read on.

Greasemonkey lets you add new features to websites by installing (or writing your own) User Scripts. Lots of them can be found on userscripts.org.

My Greasemonkey Scripts

• Fake Lion Scrollbars shows overlay scrollbars like most other applications on Lion.
  Changelog / Known issues:
  • 0.4 fixes a bug where you couldn't click on things behind the FLScrollbars even when they were invisible.
  • Had to disable it for Google Mail because FLScrollbars were inserted into sent messages. You might have to disable it for other mail services.
  • only vertical scrollbars Version 0.2 includes horizontal scrollbars!
  • you'll have to hide the real scrollbars, for example with the Stylish style Scrollbar hidden
  • you can't click and drag the FL scrollbars
  • FL scrollbars are not visible on very dark backgrounds 0.3 added a white border to solve that. It doesn't quite look the same as on standard scrollbars, though.
  • The FL scrollbar will always disappear 1 second after the last scroll event. It won't stay visible as long as your fingers are on the trackpad (or the Magic Mouse), or the cursor is moving.
  • If you zoom the page, the FL scrollbars will also get bigger (or smaller).

• Link Warning Layer shows little icons as you mouse over links to indicate the type of the link, including email links, pdf and zip files and many more. That way you don't have to look at the status bar to see what kind of link it is. Based on Link Warning Extended (see below).

Stylish is to CSS as GreaseMonkey is to Javascript: it lets you change the look of websites or of the Firefox window via CSS.

Get the extension and lots of styles on userstyles.org.

My styles

• Vertical Toolbar Fix for Lion. If you're on a Mac with OS X 10.7 Lion and want to use the addon Vertical Toolbar, then this is for you! I made this for you!
  Usually Vertical Toolbar can't be shown on Lion because either the OS doesn't send Firefox a mouseover notification when you're close to the border (due to the new resizing features), or Firefox doesn't forward it to Vertical Toolbar. Either way, this addon enables you to use it, at least on the left side. You still can't activate it by going all the way to the border, you have to move away just so much that the cursor is a normal cursor instead of the resize window cursor.
  If you want it to be more sensitive, i.e. display Vertical Toolbar sooner as your cursor approaches the border, just increase the min-width number (default 5). You can also lower it to 4, in case you find it too sensitive.
