Disabled add-on compatibility checking a while ago to try forcing some old add-ons to work. I want to re-enable add-on compatibility checking. I've tried doing this from about:config, but the information resets when firefox starts or closes. I tried putting it in user.js, but, even though the file is reloaded as firefox starts, there is no reaction as to the contents of the file. My user.js file follows: (C:\Users\h3X\AppData\Roaming\Mozilla\Firefox\Profiles\airs8akf.default\user.js) // User.js - replaces all prefs set elsewhere in mozilla user_pref("extensions.checkCompatibility", true); user_pref("extensions.checkCompatibility.3.6", true); user_pref("extensions.checkCompatibility.3.6b", true); user_pref("extensions.checkCompatibility.3.6p", true); user_pref("extensions.checkCompatibility.3.6pre", true); user_pref("extensions.checkCompatibility.3.7a", true); user_pref("extensions.checkCompatibility.4.0b", true); user_pref("extensions.checkCompatibility.4.0p", true); user_pref("extensions.checkCompatibility.4.0pre", true); // end

I believe this symptom may be caused by the Add-On Compatibility Reporter Extension. Try disabling the extension and then reset the extensions.checkCompatibility entries in about:config to default. Then restart Firefox and you should have compatibility checking back.

Remove all extensions.checkCompatibility lines from prefs.js and user.js.

Delete the files extensions.* (e.g. 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 a compatibility update available.
