> Firefox bugs are bugs in Firefox. (I also keep experiencing the stuck menu bug, but again, Firefox bug.)
Glitches in context menus could theoretically be just Firefox bugs. Glitches in the global menu bar can't be just Firefox bugs. Those pixels don't belong to Firefox. It shouldn't be possible for an application to cause the OS to lose track of which menu the user has open in the global menu bar. Even if Firefox is buggy here (quite likely), there's clearly a deficiency in the OS itself, too.
