I have been using Firefox for a while and even though I switch constantly between at least three browsers (Firefox, Google Chrome and Opera), it is still my favorite thanks to an unmatched set of features and plugins that make browsing much less annoying.
This is my list of favorite Firefox plugins.
First set is the absolute necessity, as without these I cannot surf for more than a few minutes:
- Adblock Plus
Second is rather optional, but still makes a difference
IE Tab Plus
