HI, sorry my English is not so good -hope, you understand me. Since a few weeks I have a problem with firefox: after using the browser without any problem, I close my Laptop by dialing "Ruhezustand / hibernation". When I open my laptop again (regardless of duration), Firefox tabs are "grey", cannot be longer used. I have to close the browser completely and start again, very cumbersom! What can be the problem? IOS is updated, Firefox also. No other browsers have this problem. Hope you can help me? Best regards
