Useful Firefox extensions

[riscy]

Ok peeps - those of you who use FF - what extensions/addons can you NOT live without?

For me :

Clippings - add text to a clipboard and access it later - essential
GBookmarks - copy a bookmark to a Gmail account and access it from anywhere
Video Downloader - great for grabbing vids from YouTube etc
GoogleBar Lite - excellent app
FlashGot - used with FlashGet, and other download accelerators
Paste and Go 2 - copy a web address and then click on Paste and Go
Sage - RSS feed reader
Gmail manager - read and access multiple GMail accounts

I can't live without these:

Smiley Xtra 4 - adds smileys to any post
Stop Hammertime - changes stop loading button
McAfee SiteAdvisor - lets me know if a website is bad or not
Clippings - save text for later
Dictionary tooltip - highlight word then right click for meaning
Tabbrowser preferences - enhances control over your tabs
Talkback - submits a crash report to mozilla.org
Link Preview - shows link in thumbnail
