Why Firefox is my favorite web-browser:
Tabbed Interface - Enjoy the comfortable surfing experience.
Extensions (Add-ons) - Surf the web faster, easier and still safer. Some of my favorites: NoScript, BetterPrivacy, RefControl, FireFTP, Cookie Monster, URL Suffix and Tab Mix Plus.
If you use AdBlock Plus I recommend to use the add-on with Peter Lowe's Adservers list and own custom filters, only. The easylists have tooo many whitelisted pages!
If you use uBlock Origin note that it's a general blocker, it blocks a bit more than only Ads and you can disable the Easylists, too and use Peter Lowe's list with custom filters, only.
Themes - Change the look and feel of the user interface and personalize it to the way you like with a lot of predefined Themes or create your own Themes.
Search Engine Integration - search a lot of search engines, dictionaries (Leo) and communities for terms and definitions or images, from the integrated Search Bar.
Furthermore I like Firefox cause: It's Open Source Software, clearly arranged and easy to use, depends on the Mozilla rendering engine Gecko and therefore NOT depends on any other Browser Engine, Favorites / Bookmarks can be imported / exported very easily.
