When I access the website of UGC ( https://www.ugc.fr/ ) the access page opens up but immediately freezes: the screen luminosity decreases and the pointer cease to function: I cannot acces any of the options: select movies on show, select cinema programmes or schedule, open my UGC account to reserve performances ... Nothing works ... I have tried to reduceprotecton, etc as sugested on Forum and other suggestions: nothing works. I have no problem at all when I open the same website with Opera or with Microsoft Edge ... Why it does not work under Firefox puzzles me. Can you do something about it ? I use Firefox as my defaut internet access without problems for everything else ! This is really strange and most annoying. Thanks for your help.
