unresponsive plugin pop up constantly popping up

Hi, sorry you are having problems. Mozilla labs is a set of projects, none of which should be seen or affect you unless you go looking for and install them. <br /> <sub> (Possible exception the Test pilot add-on, IF you opted for a previous Firefox Beta, then Test Pilot was offered. For background info see mozillalabs.com/projects/ -> [https://mozillalabs.com/en-US/projects/test-pilot/ Test Pilot]<sub> I suggest you try refreshing Firefox. That retains passwords, bookmarks, open tabs and plugins, but will reset some things and remove any add-ons. I suggest you Bookmark the home sites of any add-ons you may wish to re-install later. *To refresh Firefox see and use [[Refresh Firefox - reset add-ons and settings]] You also need to update Firefox, you are on Fx34 the current Release is Fx35.0.1 * Use Firefox Menu {Three bar icon) -> Help {(?) icon) -> About Firefox * See [[Update Firefox to the latest version]] Please post back to say how you get on and confirm what you have tried. If you still have a problem with some ''unresponsive plugin pop up constantly popping up'' please provide more detail about that and maybe a screenshot would help * [[How do I create a screenshot of my problem?]]
