Did you try what I mentioned?
Use a slow system (or slow it down), be sure to have Flash enabled, go 
to Google News, easiest is to make some search by date, you get an URL 
list, right-click-open-link-in-new-tab it in sequence rapidly. Assuming 
you'll have as many Flash ads as here, you may meet the problem.
Firefox does not make good multitasking, the Flash player probably 
blocks resources (why the heck does it play in the background? (spending 
CPU time showing things nobody sees)) and the focus window does not 
receive its share of processing time. These timing issues probably 
reveal a mouse driving bug that doesn't show  otherwise.
On a small computer of mine, response time and false clicks appear with 
6-8 launched windows running.
If I do the same experiment with Flash applet disabled, it's well after 
launching 20 windows that the problem starts to manifest faintly.

Also, the repeated crashes that made FF disappear without notice nor 
apologies were obviously caused by Flash.

I wonder why we he have beta software in a LTS release.
Now I enable Flash only for the time I really need it .   Way way way 

But yet, if only for trying :
Question : may I install both FF2 and FF3 to run in the same system?
