I'm presently running Firefox 3.6.8 on Ubuntu 9.04. My Firefox extensions include Ubuntu Firefox Modifications 0.9rc2. I've upgraded Firefox on this install a few times; as far as I can recall, some version of this extension was present when I initially installed Ubuntu 9.04. I have disabled it, mostly because I didn't know what it provided me, nor was I able to find out when I tried a bit.

What does the extension do?

  • This extension also disables multiprocess support. This issue appeared to be fixed at some point, but it seems we're back to having it mess with Firefox. Launchpad bug report can be found here. If you type about:support into Firefox, you'll get 0/1 (Disabled by add-ons) in the Multiprocess Windows entry.

The files here show some of the changes that Ubufox provides (custom branding, search preferences, etc.)

    It must be really difficult to provide a description, and links to additional resources, and other details, within the extension itself. Open Firefox > Go to Addons > Ubuntu Firefox Modifications > Click "more" > Your description: "Ubuntu Firefox Pack". Powerful stuff. Apr 29 '12 at 17:46
