Best Firefox Extensions

Hi yesterday i installed Firefox 3.5.2 "i have not used FF for some time" and i see it has changed quite a bit .. for the better i may add so my question is are there any (must have) add-ons that members would recommend ? grateful for any advice

There's a good download manager called "DownThemAll", which lets you pause/resume/download via multiple threads:

Also, if you use sites like YouTube alot, this plugin will let you download the videos:

Good idea for a thread, BTW!

Thank you Ian i will be looking at each

If you like to have som security while surfing, I highly recomment NoScript. I've been save many times by this extension. There is a slight learning curve as to what website you perminately allow to run scripts, but nothing I found too complicated

Thanks draceena i will be having a look at that

Dont forget use Adblock Plus, its very useful block advertisements

Yes, AdBlock Plus is excellent. I like ForecastFox also for weather updates.

Tons of Themes too!

Adblock Plus
Xmarks
Cooliris

Ablock+
Flashblock
Foxclocks
(and one I LOVE and want to see made 3+ ready) Firesomething

I keep FF as light as possible, I hate overcrowding. The only addons I use are Firegestures to enable mouse gestures for navigation (habits from my opera days!) , an extension to aid malware research and an extension called Personas for decorative themes.
