Comment 6 for bug 743135

This just started happening to me. First i noticed it on musicbrainz.org - i couldn't click on some links and i had to move to some text areas using tab. Now it happened even on Google results page. After reading comments of this bug i noticed that
mouse doesn't work on a area on screen. For example normally the mouse cursor is the text cursor when over this
text area. On a small part of the textarea mouse cursor changes to arrow and it's not possible to click on the text area.

The same arrow bug happens while over for example terminal window.

I'm not confident the bug is in Firefox, but it might be related as i noticed it first in it.

Things that might affect the bug (if it is in firefox):
  - Firefox has been running for a few days
  - There are 10 tabs open
  - Flash plugin crashed a couple of time while watching a youtube video.

I'm running up to date Ubuntu Natty on x86_64.
