Firefox 80 blocks flash

[treloar]

Up until last night I was using Firefox 79.0 on Ubuntu 16.04, I got an update to Firefox 80, now I can no longer play games on Kongregate as it seems all flash is blocked.

I can still play Kongregate games in Chrome, but as Firefox is my main browser I wish to enable functionality in it once more or rollback to version 79, can anyone inform me how to go back to 79?

I cannot even find my way to the repository for 79, only 80 is shown.

This is bug #1893021, which I'm working on.
Please note that flash support will end on December 31st this year. See https://www.adobe.com/products/flashplayer/end-of-life.html for details.

I decided to backup my bookmarks from Firefox 80 and discovered a new and interesting problem, I have now ended up with a file called bookmarks-2020-08-27.json.tmp that has both a lock and a cross on it that I cannot move, rename or delete as it does not exist but clearly does as I can see it. When I go into terminal it doesn't show up, when I try to use admin to delete it I cant either... I'm really starting to hate firefox 80

That's clearly a separate bug, would you mind filing a new report for it, so we can investigate?

Apparently its fixed now, I Googled some and found 2 things to try to get rid of it.

1. Shutdown my system completely and boot fresh in the hope that Ubuntu would clear the file itself... (which it did for me it seems luckily)

or

2. Take my Ubuntu SSD to a Windows PC and delete the file. (Not quite sure how that works unless you use LinuxReader or some other program to see the ext4 filesystem because I'm pretty sure Windows doesn't see it)

How do I close out a thread that someone has worked upon because this is now a duplicate

No need to do anything, this bug is already marked as duplicate.
