Overriding extension compatibility check for FF3.5+

Disabling extension compatibility check for Firefox was easy. Go to about:config and create a boolean value named extensions.checkCompatibility and set it to false.

Until Firefox 3.5!

(More specifically, products that are based on < Gecko 1.9.2)

Newer Firefox requires you to append version number to the variable. This will ensure the extension override wont work forever as FF is upgraded to next version. For example, in Firefox 3.6, the variable would be extensions.checkCompatibility.3.6
