Firefox Users

What Extensions and/or themes are you using regularly?
Myself...
Theme: Mythical Sirens (Yes it's girly but it's very colorful.)
Add-ons:
Adblock(Self explanatory to some degree but you can choose which ads you want to see and which adds you don't. You can also block ads on a webpage entirely.)
All in one gestures (By right clicking and drawing some symbols you can control aspects of web browsing. It's like a DS function for firefox. For example. Drawing a lower case 'h' will send you back to your home page. The functions are completely customizable.)
colorful tabs (Just colors your tabs. I like it for the subtle visual cue so I don't close the wrong tab.)
morning coffee (just downloaded this one. Giving it a trial run. Edit: I like this one. If you have a daily lists of things you check you can put them in this add on by day of the week or everyday and it will open all the sites in tabs for you. I only wish I didn't have to actually open the add on to add the web addresses. Overall, I am pleased.)
pdf download (Gives you the option to download PDFs either in Firefox or with and outside program. I don't look at a lot of PDFs but it takes a while to DL in Firefox so I might keep it as a convenience.)
Session manager (You can save a browsing window with all of it's tabs. I especially loved this in school because if I was drawing up research I could save the session and visit it later without adding all of this webpages to my favorites. I still use it like this.)
Firefox is by far my favorite web browser.
