Beta Repository for making Firefox 4 coexist peacefully with 3.6 on Fedora 13

Filed under: Blog — admin @ 9:45 pm

Firefox 4 offers some compelling features such as HTML 5 improvements and a new add-on manager. Since it’s quite painstaking to compile the beta from source and quite messy to place pre-compiled binaries in system default folders (not to mention the compatibility checks and upgrade chores that would interrupt at each launch if you go back and forth between different versions), I created a repository at which can be used to test the beta version without touching any 3.6 stable release already installed on the system:

Firefox 4 Beta 1 Menu Shortcut

To use the repository, issue the following commands:

$ su -c 'wget -O /etc/yum.repos.d/inspirated.repo'
$ su -c 'yum install firefox-beta'

The beta refuses to run if an instance of old Firefox is already active. Therefore, close the older Firefox and then launch the 4.0b1 version using firefox-beta command or the “Firefox Beta” shortcut in the applications menu. A new profile shall be created at ~/.mozilla/firefox/beta/ in order to leave your older profile’s settings, bookmarks and extensions etc. intact.
