I can start a youtube video but the mouse will not click on "skip ads" or pause the video or move the video to different times within the video. The same thing happens on other sites, for example I can click on walmart.com and then all other clicks will not function cannot proceed any further within the site. I have uninstalled/reinstalled firefox, I have tried safe mode and I have disabled all add ons. I use the default theme and nothing works. This was not an issue prior to the most recent update. The only way for me to post this is via Edge and edge is crappy.
