Filesystem dialog will not show up for uploads in Gmail, Google Drive and other non-Google webmail
I am on MacOS. I am using the most recent version of Firefox (75.0). When I go to upload a file in either Gmail or Google Drive, the filesystem dialog will not come up. The browser freezes for a few seconds, I get the beach ball, then it comes back with nothing have happened. I have refreshed Firefox completely, I have tried this in safe mode without any extensions, and none of it helps.
I tried a non-Google webmail solution as well and the same thing happens.
