I would like to share some firefox addons that I think are really useful just incase no one has heard of them.. If you have any that I don't have please share.
1. Adblock Filterset G Updater - https://addons.mozilla.org/en-US/firefox/addon/1136
This synchronizes adblock to download a list of websites that give ads and blocks them. (works really well).
2. Adblock Plus -
https://addons.mozilla.org/en-US/firefox/addon/1865
This lets you block all sorts of things and create custom filters it can even block flash..
3. DownloadHelper
https://addons.mozilla.org/en-US/firefox/addon/3006
This lets you download various things like .swf and other videos and sometimes music from sites that stream it.
4. Greasemonkey
https://addons.mozilla.org/en-US/firefox/addon/748
This lets you run differnt scripts that people make which can range from blocking ads to improving a sites functionality.
5. ReloadEvery
https://addons.mozilla.org/en-US/firefox/addon/115
This lets you reload pages after a certain amount of time repeatedly
6. Downloads in Tab
https://addons.mozilla.org/en-US/firefox/addon/4526
This lets you open the download window in a new tab instead of window
7. Snap Links
https://addons.mozilla.org/en-US/firefox/addon/4336
This lets you hold down right click and drag a box over links and when you release it will open them all in a new tab.
8.Speed Dial
https://addons.mozilla.org/en-US/firefox/addon/4810
example:https://addons.mozilla.org/en-US/fir...preview/4810/1
This gives you similar to operas speed dial feature. its a slight bit slower though but its worth it because i like firefox better than opera..
