Facebook videos not playing on Mozilla (but working on Youtube) - 16.04

Question

Facebook videos stopped playing but on youtube everything is still fine.

When I play videos on Facebook I get:

"Something Went Wrong, we're having trouble playing this video".

I already did:

1) Update

sudo apt-get update        # Fetches the list of available updates
sudo apt-get upgrade       # Strictly upgrades the current packages
sudo apt-get dist-upgrade  # Installs updates (new ones)

2) Restart PC

3) Tried chrome (everything working)

4) Click on Learn More - it says I should update and restart my browser.

5) Remove and install Firefox Web Browser and Adobe Flash Plugin from Sofware Center

6) Completely remove Firefox and Adobe Flash Plugin as recommended Here and here

As nothing has changed, what else should I try?

(Using Ubuntu 16.04)

Solution 1

Installing ubuntu restricted extras solved this problem for me

sudo apt-get install ubuntu-restricted-extras

Solution 2

I had the same problem. I fix it like this:

sudo apt-get install adobe-flashplugin

If that's already installed, try to upgrade it:

sudo apt-get upgrade adobe-flashplugin

Solution 3

I have the same problem, and this solution works for me. You can find "Restart with Add-ones disable" in "Help" menu, the firefox will restart with safe mode, check the video works or not, then switch back to see how about it then.

Prior to installing ubuntu-restricted-extras, did you have a Flash plugin installed, and if so which package was it?

[vanillaSugar]

Yes I have installed adobe-flashplugin and also tried to update it.

OK! This is really useful to know. So when you installed ubuntu-restricted-extras, which installs flashplugin-installer, did it remove the adobe-flashplugin package? You can check with the command apt-cache policy adobe-flashplugin flashplugin-installer

It seems that I have installed adobe-flashplugin package but not flashplugin-installer. pastebin.com/Z5JB1ywF

you need to enable canonical partners in other softwares tab of software and updates software

NOT installing adobe-flashplugin and applying this solution worked for me.

also solved my problem on Ubuntu 20.04 on a new install, when other solutions didn't. Thanks!
