Just few days ago firefox 3 was released for download and many of you lost your favorite add-ons I know! I did too!. Even after hiting update button I still got message it is not compatibile with firefox 3.

This is what I did. I removed all my add-ons (7 of them) and went to firefox addons website after then I looked up all add-ons and re-download them.

Restarted my firefox 3 and they are all back!.

Few addons that I recommend:

Firebug

Seo for Firefox

ScreenGrab
