[Bug 1022817] [NEW] clamping

[Arthur Lyrio]

Public bug reported:

Firefox is locking, especially when I want to see videos.
Has lag, and sometimes, the firefox window don't appears more, but i can hear the song of the video playing on the background. But i cannot open that anymore. Not with the ALT+TAB.
Then i need to open other firefox, and every time when i minimize the firefox, it just hide itself.
Some times it just stop to work, but i don't know why. Just an error of ubuntu appears,  and the firefox closes.
I'm using ubuntu 12.04
Thanks for the atention, and sorry about my english.
I'm brazilian, and i'm learning english, so may you find some gramatical errors on my talk.
