Install Firefox 4.0 on Ubuntu 10.10

Using the Firefox daily builds PPA may have been fun for testers and early adopters, but now that Firefox 4 is officially out there's a build available on a Firefox stable channel PPA. If you're itching to upgrade to Firefox 4 but aren't willing/able to upgrade to the currently in-development Natty, here's your answer:

~$ sudo add-apt-repository ppa:mozillateam/firefox-stable
~$ sudo apt-get update
~$ sudo apt-get upgrade

There's another way to do the upgrade using Ubuntu Software Center that many would probably be more comfortable with. Either method will give the same results, so choose your poison.

Firefox add-ons update check
Generally, it's pretty safe to upgrade using a stable build PPA but even then there's a small amount of risk. For example, I found the language and ubufox add-ons aren't compatible with Firefox 4.0 right now. Upgrading to Firefox 4 will disable these add-ons until they're up to speed. That's just the obvious issue. I haven't noticed anything else yet. If you're not comfortable with even that, I'd suggest waiting for Natty's official release next month.

On a side note, those curious about download stats for Firefox 4 will probably like what they see on Mozilla's download stats page. It's a nice real time map of downloads worldwide, but be warned that it can lag older browsers and machines.

Reverting back to Firefox 3.6

Firefox 4.0 on Ubuntu 10.10 currently seems to have some issues with Flash 10.2. At least, it does on my computer. If things aren't going as well as you'd like then it's a simple command away to revert things back to the older Firefox 3.6:

~$ sudo ppa-purge ppa:mozillateam/firefox-stable

That should take care of things.
