Facebook videos won't play on FireFox

When I try to play any video it does not play. I can view the thumbnail and the play button but pressing it just loads for a while and then it shows the same (thumbnail and play button).

I am using Windows 10 and after recent updates that I had this started happening. I have checked that: - I can play YT videos - I can play both flash videos and games - It does not work on FireFox and Edge but it works on Chrome And I have tried: - Updating FireFox - Updating Adobe Flashplayer - Refreshing FireFox - Installing the Media feature pack for Windows - Starting FireFox with Add-ons disabled - Disabled "Use hardware acceleration where available" - Reconfigured FireFox in Windows Defender Firewall with its plugin container - Tried to untick "Block dangerous and intrusive content" - Checked if Facebook is blocked by Adobe Flash Player and allowed it everywhere - Tried to ipconfig -flushdns - Deleted my additional entries in the hosts file of Windows(although they have nothing to do with videos or Facebook)

I am out of ideas now so please give me any possible support.

How was your FF installed? When you did this was all older FF uninstalled and Mozilla folders deleted prior to the update.

No, FireFox was installed before the update and I have re-installed it at least 2 months ago(still after the re-install I think FB videos were working)
