GreaseMonkey Addon is disable after I did enable it and then restarted Mozilla Firefox. Why?

Posted

First day, I installed GreaseMonkey and it is ok and works. And Second day, I open MF(Mozilla Firefox), It asks me to enable GreaseMonkey. I make it enable and it says it needs to restart MF. I restart MF but it also asks me to enable GM again.

It is possible that there is a problem with the file(s) that store the extensions registry.

Delete the extensions.* files (e.g. extensions.sqlite, extensions.ini) 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 or not compatible extensions in "Firefox/Tools > Add-ons > Extensions" then click the Tools button at the left end side of the Search Bar ("Find Updates" button in older Firefox versions) to check if there is a compatibility update available.

If this hasn't helped then also delete the addons.sqlite file.
