AdBlockPlus
Hide Menubar (nameless)

 

• adblock plus: undeniably the best add-on ever.
• greasemonkey: Simply amazing. Surprised nobody else so far mentioned this.
• auto pager: Automatically loads next page (for example, on google search, it'll load page two directly below page one). Settings are customizable (but very complicated) and you can add your own websites.
• smooth wheel: Bunch of settings to customize scrolling speed, smoothness, etc.
• quickdrag: simple, customizable mouse gestures.
• search preview: adds preview of webpages on google search.
• quick search bar: makes searching much easier. Replaces search bar with the icon of each search engine you have installed. you can just drag/drop text onto the icons to search on which ever engine you dropped on.
• flash block: functions much like NoScript, but I personally think it's better.

 

Addblock plus (like everyone else)
Addblock plus element hider helper (manually disabling things on sites is nice)
Autopager (removes the need for clicking next page on forums and such)
Add-on Compatibility reporter (usefull of addons refuse to put a higher number in the compatibility list)
Download Statusbar (removes the need of using that awful downloads menu)
DownThemAll ( download manager)
Flagfox (lets me see where sites are hosted)
Greasemonkey (duh)
gTranslator (easy google translator)
HTTPS-Everywhere (uses https instead of http whenever possible)
TinEye Reverse image Search ( looks up images on tineye)
WOT (checks if A site is reliable)
Ghostery (removes all the statistics BS from sites most sites have at least 3 of them GBAtemp only has google analytics btw)
Those are only my favorites I have installed a lot more addons than this

 

I hardly use any lol.
But.. chatzilla I suppose.(even though I dont use it on my PC much).

 

Google does have a preview feature that comes up when clicking on the description of the webpage, but I don't like it. >_>

the addon inserts a preview for every webpage in a thumbnail-like style.

Warning: Spoilers inside!

AdBlock Plus - Must have. Just don't use it on 'Temp >-p
NoScript - Usefull, but can be pain sometimes... Somesites just don't work, even if I temporarily accept everything, so I need to disable it.
TabMix Plus - How can you survive with just the normal tab options?

Text to Link - Can't live without it (oh, drama). It allows you to doubleclick a a url that is just plain text.
Image Zoom (i think that's the name... I'm at work now) - Allow you to zoom an image using right mouse button + wheel to zoom in and zoom out.
Flashgot - It's nice, period.

BugMeNot - Allows you to access some sites you'd need to register before.
Show Image - When a picture doesn't load, this let you to just reload it, just like on IE.
Open On IE - Nobody here uses it? Opens the current site on Internet Explorer.

I think there are some more i use, but i can't check right now.

 

Google Chrome.

 

Noscript
Ad Block Plus
Nightly Tester Tools
Greasemonkey

I used to be so attached to TabMixPlus, although recently I've just grown away from it, other than that I don't really have any other addons clogging up my browser.

Also why do people use all these Youtube downloaders and Youtube to mp3 converters? Don't people just use JDownloader?

 

Ad block I'm not sure which add on is good
