I have already run into it with Firefox. Currently using for main page and forums Torch version 65.0.0.1613 (32 bit) for a number of places and it runs flash content just fine.
I believe that WGT changed something a short while back. I had not updated neither flash nor Firefox, but all of a sudden I was having to re-enable flash on every page. Already had Torch installed, started using it and it worked fine. Every once in a while I have to tell it to run flash but normally not.
