Other performance changes include significantly faster startup times when restoring lots of tabs and settings that let users take greater control of our new multi-process architecture. We’ve also upgraded the address bar to make finding what you want easier, with search suggestions and the integration of our one-click search feature, and safer, by prioritizing the secure – https – version of sites when possible.
Before you install Firefox, make sure that your computer has the required libraries installed. Missing libraries will cause Firefox to be inoperable.
The installation file provided by Mozilla in .tar.bz2 format does not contain sources but pre-compiled binary files, therefore you can simply unpack and run them. There is no need to compile the program from source.
