I'm not able to click on my LinkButton in FireFox when I have either of the following extensions enabled:
- AdBlock Plus
 - Disconnect
 
Any idea why this could be happening and what I could do to get around it? I've tried CausesValidation ="false" to no avail. It seems like the javascript:__doPostBack() function is just never called when these extensions are enabled. 
                        
Here's a fuller answer, but I had a click event binding to my LinkButton looked like this:
Because of this the Javascript on the LinkButton was getting completely ignored and the
__doPostBack()was not firing.
