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