Firefox crash when mouse over history icon

If I hold Alt key and press s key it will open up history, but if I click on anything it will crash, I just did it.

Try the mozilla ppa, it may help

What is mozilla ppa, program, website?

sudo add-apt-repository ppa:ubuntu-mozilla-daily/ppa; sudo apt-get update; sudo apt-get --reinstall install firefox

Should do it

No good, still crashes. How do I back this version out and go back to straight firefox?

sudo ppa-purge ppa:ubuntu-mozilla-daily/ppa; sudo apt-get update; sudo apt-get --reinstall

I'd log a bug, you may have to use a different (better) browser til it gets fixed.

Namoroka browser still there, did not remove it and replace with Firefox, also it is trying to push packages to Thunderbird...

ok then remove the browser, and the ppa. Then reinstall the browser.

If you rename ~/.mozilla so you get a vanilla profile, is it the same?

Sorry, but i don't know how to do that? I was able to remove firefox via the ubuntu software center, but not sure how to gfind ppa and remove. If you can send the commands i'll cut and paste into a terminal session again. that's my extent of knowledge of linux.

If you use the software sources app in system -> administration

You can remove it there
