Firefox Plugins I Recommend (…and I use)
Slylish
Allows you to change the CSS of any page on the web. There is a large community already that have made scripts for you to use. Simply use the ‘find scripts for this page’ feature. Great for removeing text ads from Facebook, Google etc.

Adblock Plus
Removes LOADS of ads from the net by subscribing to a list of known ads. Also has the ‘open blockable items’ feature so you can scroll through every thing that is visible on that page and block it or right click and select ‘block this’. It even has tabs for flash and Java so you can block those ads too.

Adblock Plus: Element Hiding Helper
Similar to that found in the Web Developer toolbar outline function, this allows you to mouse over a webpage and see the outline of the current element and then block it in Adblock Plus.

Adblock Filterset.G Updater
Updates the filterset every 4-7 days.
ADD IT HERE
Foxmarks Bookmark Synchronizer
Allows you to save your Firefox bookmarks to a server and synchronize them up and down. Useful if you have more than one machine or are constantly re-formatting like me.
ADD IT HERE
Web Developer
An invaluable tool for any web developer out there regardless of ability. The tool I use the most is the ‘outline current element’ tool which draws a red line around the element the mouse is over and show the deprecation in the address bar. very helpful for understanding CSS problems.
ADD IT HERE
Google Preview
Shows preiews of pages next to the search result in google. Similar to that already done when YouTube videos appear in the search results. Uses the image taken from google’s webcrawler.
ADD IT HERE
del.icio.us
An integrated system for taging pages in your del.icio.us page. Comes with a menu bar as well as two menu buttons ‘tag this’ and a direct link to your del.icio.us page. Also feature right click integration.

Hi!
