Adblock Plus
Adblock Plus allows you to regain control of the internet and view the web the way you want to. The add-on is supported by over forty filter subscriptions in dozens of languages which automatically configure it for purposes ranging from removing online advertising to blocking all known malware domains. Adblock Plus also allows you to customize your filters with the assistance of a variety of useful features, including a context option for images, a block tab for Flash and Java objects, and a list of blockable items to remove scripts and stylesheets.
Starting with Adblock Plus 2.0 there is an option in Filter Preferences to allow some non-intrusive advertising. The goal is to support websites using non-intrusive ways to advertise and to encourage more websites to do the same.
Adblock Plus Pop-up Addon
By default, Firefox or Adblock Plus doesn't block any pop-ups that are opened on mouse clicks or other user events. This addon complements Adblock Plus with the pop-up blocking functionality.
There are two ways of getting rid of an unwanted pop-up with this addon:
- Adding the pop-up's url to Adblock Plus' filters. This will block just the individual pop-up (or any other pop-up which matches the pattern you decide to write).
- Creating a site rule in this addon's preferences for the opener site. This will prevent the opener site from opening pop-ups completely. This is especially useful for sites that change their pop-up urls frequently.
You can do both of these tasks easily by right clicking on the pop-up window and selecting "Block this window".
ColorfulTabs
The most beautiful yet the simplest add-on that makes a strong colorful appeal. Colors every tab in a different color and makes them easy to distinguish while beautifying the overall appearance of the interface. For Seamonkey & Flock. An essential.

FoxyProxy Standard
FoxyProxy is a Firefox extension which automatically switches an internet connection across one or more proxy servers based on URL patterns. Put simply, FoxyProxy automates the manual process of editing Firefox's Connection Settings dialog. Proxy server switching occurs based on the loading URL and the switching rules you define.
Animated icons show you when a proxy is in use. Advanced logging shows you which proxies were used and when. QuickAdd makes it a snap to create new URL patterns on-the-fly. FoxyProxy is fully compatible with Portable Firefox, has better support for PAC files than Firefox itself, and is translated into more than 34 languages.
