Turn off video auto play in Firefox

Refer: https://support.mozilla.org/en-US/questions/1222694

about:config?filter=autoplay

Helpful Reply
The pref that controls auto-play has been changed in the current Firefox release (63.0.1) to an Integer value.

media.autoplay.default = 0

When the first two prefs listed below (or at least user-gestures-needed) are true then there is also a setting available in "Options/Preferences -> Privacy & Security -> Permissions" and you can inspect and modify the exceptions.

media.autoplay.enabled.user-gestures-needed = true
media.autoplay.ask-permission = true
media.autoplay.default = 0 [0=Allowed, 1=Blocked, 2=Prompt]
You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

Trying to fix suspend

Refer: https://www.dell.com/community/Inspiron/Suspend-resume-problems-on-Ubuntu-18-04/td-p/6072410

Re: Suspend-resume problems on Ubuntu 18.04
It is the buggy nouveau driver again. That's what solved the issue for me.
Edit the file /etc/default/grub.

$ sudoedit /etc/default/grub.
Add "nouveau.modeset=0" to the line that says GRUB_CMDLINE_LINUX then press ^O to save the file and ^X to live then run.
