One of the beautiful things about Firefox as a browser is how customizable it is.  According to my stats, the vast majority of people reading this blog use that browser so I thought I'd pass along this site that I had bookmarked: I Want A Firefox Extension To... which is a collection of over 200 extensions that add functionality to the Firefox browser in areas from Ad Blocking to Links to Weather.

I think I may have listed this elsewhere on the blog already but there are some new ones on the list since then so here is a list of extensions I have installed.  My absolute favourites are in bold italic (I'm too lazy to add links to all of them but just do a Google search on any of their names and you'll find them) :

Adblock
- blocks ads (duh)

AddBookMarkHere
- helps control where bookmarks get added in your folder structure

AlwaysRememberPassword
- just like the name says, useful for banking sites and others that tend to clear your password, even if you told the browser to remember it.

Answers
- ALT-right click on any word to get a definition and other information

Colourful Tabs
- makes your tabs different colours which helps usability way more than it sounds like it should! 

CopyURL+
- allows you to copy to the clipboard the current document's address along with additional information such as the document's title, the current selection or both.

CustomizeGoogle
- just like it says, provides all kinds of hacks to make Google more usable

delicious
- adds buttons to your navigation bar for quickly adding bookmarks to Delicious

DOMInspector
- provides easy access to meta information about a web page

FoxyTunes

- allows you to switch to Internet Explorer without leaving the Firefox browser.  Useful for those sites that are still only accessible in IE.

MetaFilthy
- tracks various information about your reading habits on MetaFilter

PDFDownloader
- provides a few extra options for reading PDF files

Screengrab!
