I have a desktop running Win 10 Home 64bit 1909 with FB74 as browser. When I open Youtube, I can access videos without problem. However if I click a Youtube link within TBemail the screen below appears and video is inaccessible. Using either Edge or Chrome there is no problem, video opens OK. I also have a Samsung R520 laptop also running same Win spec and when I click Youtube link in email the video opens and runs in FF OK!

Any help with overcoming this problem welcome. Would I need to save my profile, delete and reinstall FB to solve problem

Hy there! I think you may need to update your browser or clear the cache.
