Youtube search doesn‘t work, leads to GFX-type problems
For years I didn‘t have any problems using Firefox and Youtube; it started yesterday: When I try to search for anything the result is chaotic; the first 1-5 seconds it get black squares on my screen, pictures of videos, no text/descriptions etc. After 5-10 seconds everything goes white/grey without any pictures/text etc.
I tried everything: Newest/blank Firefox installation, older Firefox versions. Today I even formatted my system (Windows 7 x64 HP) because I was suspecting some kind of GFX (Nvidia) error. But no, everything stayed the same. I now tried SRWare Iron and Opera, both work fine with Youtube and my system. Only Firefox seems to have some kind of problem which for me (engineer/Germany) is undefinable.
So, now I need help. Because I love Firefox and want to use it on every page, when I need it, including Youtube...
Thank you, best regards Chris K.
P.S. I tried to upload my screenshots here, but it doesn‘t work either. I uploaded the pics into my web.de Account, here is the link: https://cloud.web.de/ngcloud/external?guestToken=YOXT0N10RLOcEwCZj19stg&loginName=christoph-koj
