"Enable Overlay" worked fine for me the first two weeks. Then suddenly, it stopped working. I've restarted my MacBook, restarted Firefox 8.01, and even remove and reinstalled Pixel Perfect. So now it's completely unusable. Help!!

I'm also having the same problem with Pixel Perfect as Jackdesert:

Have tried it on two separate machines:

Windows 7
Firefox 10
Firebug 1.9.1

and

OSX Lion
Firefox 10
Firebug 1.9.1
