Bottom Line

Firefox is the best customizable browser thanks to its stellar options (with a dizzying array of features), speed, privacy and security. Firefox offers multiple search engines that are easy to use, great ways to organize tabs and a simple, easy-to-use interface. It isn't the fastest browser on the market, but is a solid choice for consumers whether they're using default settings or creating their own personalized browsing experience.

Performance

Fast, customizable and easy to use. While Firefox faces stiff competition from Google Chrome --  which has significantly boosted its features without compromising speed -- Mozilla's browser can be whatever you want it to be: A secure search engine; a private browser; a shopping center; a place to easily manage your tabs and research; a central hub for your browsing that can be used across devices. The options are endless. This is made possible thanks to Firefox's extensive add-ons (about 3.7 billion add-on and extension downloads and counting), customizable features and easy-to-access privacy settings. Is it the fastest? No. But this simply designed browser is by far the easiest to customize, and it offers privacy, security and browsing at a decent speed.
