Mouse cursor activates items about 1cm above position

When I move the mouse around ANY web page, contextual items from 1 to 1.5cm above the mouse position are activated. This includes not only items within the web pages, but also tabs and buttons in the main Firefox application. I have been unable to get a screen shot, as Grab deactivates what is happening on the Firefox screen.

I am running Firefox 12.0 on OSX 10.7.4 on a MacBook Pro.

This problem has persisted for about six months and I've had no luck clearing it up despite the following actions: 1. Deleted and re-installed Firefox 2. Deleted Mozilla preferences 3. Disabled add-ons and restored from backups

When I start the browser initially (or after a reboot) Firefox works fine, but after changing web pages a few times, the problem may be seen again. The result is that I can't click on areas within the web page I'm interested in because the items above are the ones activated.

Can anyone help?

-> Start Firefox in -> Diagnose Firefox issues using Troubleshoot Mode to check if your add-ons/extensions are causing the problems.

Check and tell if its working normally while using Firefox in Diagnose Firefox issues using Troubleshoot Mode.
