I'm getting a strange behaviour in Firefox 20 that I don't see in Firefox 19, but that I can't really find a source for. It's largely repeatable for me, but it's not easy for me to reproduce in other settings.
In essence, I can end up with a select that I can open, but when I click on an item in the selector, nothing happens. Javascript events don't seem to fire, it's just like the item can't be clicked. Once this happens, I can close and re-open firefox and repeat the behaviour as often as I like on the same drop-down. I was able to reproduce it with a simple test case here:

But, strangely, I wasn't able to reproduce it with a local HTML file; not sure if that's relevant, or perhaps I just failed to exactly reproduce the scenario in some way, because it's not clear to me what the trigger is.
If i reload firefox in safe mode or reset firefox (in the --safe-mode dialog), this problem will go away for a bit, but it will come back. I have not yet been able to reproduce this when I don't have the Google Web Toolkit (GWT) plugin installed, but that may simply be because I'm trying to use firefox for GWT development, and when I can't trigger the behavior, I go back to doing development work until I the problem recurs. I don't know for certain that it can or cannot be reproduced without the plugin.
Although now that I think of it, I should try removing the plugin now that the problems back and see if it will make the problem go away again. That won't guarantee that you don't need to install the GWT plugin to make it occur, of course, but it'd be one more piece of data on reproducibility.
