User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10

I develop extension. In it I have a button which appears when user puts mouse cursor over the flash video.

To show it I use this code:
var panel = document.getElementById ("fdm_fmb_panel");
panel.openPopup (elemFlash, placeType, 0, 0, false, false);

To hide, this:
var panel = document.getElementById ("fdm_fmb_panel");
panel.hidePopup ();
var menu = document.getElementById ("fdm_fmb_menu");
menu.hidePopup();

It works fine most of the time. But in some rare case the button can just sit there. It does not disappear after I call panel.hidePopup and its state remains "open". Or backwards, it can became to not appear anymore, openPopup does not show it. It can even stop from drawing itself and draw the button shape only.  

I call hidePopup from timer. Maybe this bug is due to non thread safe code of Firefox.

Also I have Flashblock and AdBlock Plus extensions installed.

Reproducible: Sometimes

Steps to Reproduce:
1. Open several tabs with flash video.
2. Quickly move mouse to video and from it so my button appear/disappear.
It's hard to reproduce, it can take more than 3 hours. But sometimes 1-2 minutes can be enough.
Actual Results:  
Described above.

Expected Results:  
Descibed above.

I removed timers from my code. But the problem still exists.

You should check if the issue persists in the Firefox 4 nightly. Also, a minimized testcase could help.
