Replacement of Firefox in Ubuntu

Bytes

Due to debugging needs, you need to replace the Firefox release version on Ubuntu with the daily Firefox build version.

First, download the Linux version by using the Ubuntu 12.04 64-bit command to download the 64-bit compiled package.

First, extract the package.

Tar-jxvf firefox-16.0a1.en-US.linux-x86_64.tar.bz2

Then, move the extracted directory to the/usr/lib Folder:

Sudo mv firefox/usr/lib/firefox_night

Then go to the/usr/bin: cd/usr/bin directory.

First Delete the existing link sudo rm-rf firefox

Then create a link:

Sudo ln-s/usr/lib/firefox_night/firefox

If firefox is enabled, disable it. Otherwise, start it directly, and switch to the version of nightly.
