Alright here is a list of the plug-ins I live and die by on Firefox:

1-click weather
I like this better than forecasterfox

adblock plus
Keep all those pop-ups and banner ads hidden automatically updates with new bad stuff

User Agent Switcher
This allows you to change what the webserver sees your browser as this helps you with those sites that block Firefox.

Auto Copy
Just select the text and it gets copied to the clip board

autoHideStatusbar
Auto Hides the status bar to give you more room

Copy Plain Text
Works with Auto Copy so that when the text is selected it just copies the text not the formatting

Download Statusbar
Clean up that damn download menu and makes it a nice toolbar on the bottom auto hides when not in use

FireFTP
Nicely integrated FTP client

Fission
Adds the loading bar as the background to the address bar. (Safari thing)

MediaPlayerConnectivity
Lets you choose the media player to play rich content (great for linux)

Mouse Gestures
Turns your two button mouse into a super navigator

Tab Mix Plus
Adds tab features and options

Tiny Menu
Shirks menu bar to just one link so you can consolidate everything to one line

TinyURL Creator
Right click and create tiny URLs to links or current pages great for compacting long URLs for emailing the fam or anyone

IE Tab
Of course IE Tab for those sites that have issues with firefox

To completely disable the yellow plugin bar that tells you that you’re missing plugins, in about:config set the preference plugin.default_plugin_disabled to false. There is currently no way to disable the bar for only certain plugins or for certain sites.

So if you haven’t noticed Firefox eats memory like a mofo. This is becasue of a fast-back fast-forward option that they have. Basically firefox caches in memory up to the last 8 pages you have been on. This tends to eat away at your memory, if you have a fast internet connection I would disable it.

To disable it goto about:config in firefox in a new tab, in the filter box filter for browser.sessionhistory.max_total_viewers, then double click and change the value to 0

So I am always about making my firefox experience more exciting. This nifty little tool lets you preview your tab before you click on it. Considering I usually have about 8 tabs open this is a great help

So Firefox 1.5 is out on the mirrors now. Updates include a better control interface, number of bug fixes, and a automatic update tool so you do not have to reinstall firefox completely for new updates (after this update) also includes compatibility with CSS 2.0 and 3.0
