I was a bit confused about which bug was there first, but #1689538 reports the same issue (for me it only started on May 9th), also with Firefox, and #1689342 is about Chrome.
I have the same problem (triggered by Firefox 3x now), and have nouveau installed as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1686568 Title: Firefox Does Not Respond.
