I was forced to set system date to 01.01.2013 to install windows update. After some time Firefox (it was enabled while update was installing) have disabled all the addons due to "can't verify it" problem. OK, I've finished updating windows and set actual system time back. But now Firefox refuses to enable my addons cos every my plugin is "Unverified" which actually isn't true. I have not found any button "Check it again" or something like this. What can I do now to make Firefox recheck and enable them? Am I should uninstall and install EVERY my addon to make it enabled again? Restarting Firefox/windows isn't helps. Disabling signature checking isn't works anymore, too. Firefox 49.0.1, win 7.

In the Add-ons Manager > Extensions tab, see the "Gear" at the top and use the Check for updates menu item to have the extension manager check for updates and hopefully "force" the extension manager to become reset.

Suddenly, Check for updates hadn't helped, too. But after few hours my problem got fixed on it's own. Seems like Firefox rechecks addons on timer and it cannot be called directly.
