I personally like

Open it online

and many others that i dont remember now...

 

SearchStatus SEO Toolbar
Firebug

 

As a webmaster I think Search Status is must have add on.
It halps me alot while researching for backlinks and indexed pages of any site. Kinda Handy tool.

Also I wrote a small tutorial for using proxy in firefox.

This may help you to manually change your IP while browsing.

 

I Love The TAB EFFECT Add-On (doesn't work with FF3 yet - in development)

Rotates The Tab in 3D

 

i Love Firefoxe Security Tab

 

I really like Flashblock and Adblockplus.

 

I like FoxClocks, Flashblock, Search Status

 

Thanks for sharing this! Very Useful!

 

Still the same old method i used to..

 

I used some of the tweaks. Good stuff.

 

Extended status bar (status bar with speed, time and percentage...).
Right click link (opens selected text in a new link).
And download statusbar (manages download from a tidy statusbar.)

 

Could people link to the add-ons please.

Thanks!

 

Another FF 3 add-on I find quite useful is Session Manager.

 

Firefox is popular and powerful because of the powerful addons/plugins .
As a webmaster, google toolbar is necessary at least.

 

I use SEO for FF every day : URL="http://tools.seobook.com/firefox/seo-for-firefox.html"

 

Well I am using SearchStatus as it is best for webmaster like us and most important. I also use Adblockplus, I really like this which makes my browsing better.
