Buttons on Gmail and elsewhere not working since 138 update
I've been using Firefox from its beginning and reply on some of its unique features for my work. Since the 138 update I've been struggling to manage with things that have always worked before not working any more. I just updated to 139, and they are still not working.
In Gmail, the delete and mark as unread buttons don't work - I click on them and nothing happens.
In YouTube, from the home page I can't open any video - when I click on the image or the title nothing happens. I have to use another browser for this most basic functionality.
I am using Windows 10 Pro with latest updates on a desktop computer with 16 GB RAM.
