Your best browser extenstions

[Fork_Q2]

Anyone be so kind as to recommend any browser extensions (Firefox*/Chrome/Opera) you use regularly?

I don't use many, but I do use the following:

WikiWand
AdBlock
Flashblock
Vimperator
Enhanced Steam
Reddit Enhancement Suite
Spreed
Fasterfox
Chrome Remote Desktop
Auto Replay for YouTube

Wondering if there are any hidden gems I don't know about. Many thanks!

*Preferably Firefox

For Chrome I use Pandora Listener, RadioEnhancer, and AdBlock. When I'm on Firefox I just use AdBlock.

AdBlock on chrome. Finally i won't have to deal with annoying ads that eat my bandwidth for no reason.

• Google Mail Checker[chrome.google.com]
  
• µBlock[chrome.google.com]

I recently started using NoScript on Firefox and it seems pretty neat.

Well, not counting the basic stuff like Flash/Silverlight/Acrobat, the only "real" plugin that I use is Enhanced Steam.

EDIT: I forgot Firebug (or whatever it's called). I don't use it a lot since I'm not actually in web-development, but it's occasionally useful. Not on a daily basis, though.

I like "turn off the lights" for firefox. Dims everything but video when playing.
