Using build 12/04 on Linux 1)Disable View/Sidebar (from a "normal"sized sidebar) 2)Enable View again(I closed Mozilla inbetween) =>The Sidebar showed up, but at the smallest possible size So far, so good: Now try to resize it. A pointing hand shows up as mouse icon when you move about the resize bar, and pulling leads to a ****** GENERAL DRAG ******** in console, but it does *not* resize. I can't use it anymore *sniff*.

sounds like a dup of 14685, if you restart again, it should be open *** This bug has been marked as a duplicate of 14685 ***
