Key symptoms are:
The mouse doesn't appear to register clicks in the Firefox window (though you can move the pointer)  - but it can vary how much of the window is affected.  I have had it where the mouse simply doesn't work at all. OR where you can select and click menu items and tool buttons but not the links on the webpage.  
(NB in some instances even tne Windows toolbar at the bottom of the screen is
affected so you can't click those.  But this behaviour only happens in Firefox
- as soon as you alt-tab to another window everything works normally again.)

However, if you alt-tab out and then alt-tab back into Firefox, everything then works OK - but only until another you display another web-page, when the same problem re-emerges.  Makes Firefox unusable and I have been using it for 5  years.  Sad. Entering this from IE.
