Since updating to Firefox 6.0 each time I start Firefox it checks my addons for compatibility. This is annoying. How do I stop this behavior?

Every time I start Firefox 6.0 it runs the addon compatibility check.

Chosen solution

Try:


You can also try to delete the files extensions.* (extensions.sqlite, extensions.ini, extensions.cache, extensions.rdf) and compatibility.ini in the Firefox profile folder to reset the extensions registry. New files will be created when required. See "Corrupt extension files":

If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to do a compatibility check or see if there is an update.
