Attached files won't upload in Gmail.
Since the Firefox 72 updates on Windows 10, I have been unable to attach files in Gmail. I tested the same account in Chrome and Opera and there was no problem. File size not the issue (one file I tried was only 18K). I tried clearing the cache, history, etc., but it had no effect. Safe mode didn't work either. Neither did a reset.
