The whole system freeze is suspicious, may be out-of-memory or desktop/window manager/kernel crash. Can you inspect log from last boot, i.e. run on terminal

journalctl -b -1

and check end of the log?

[Martin Stránský [:stransky] (ni? me)]

Or you can run

journalctl -b -1 -r

to see log in reverse order.

I have rebooted several times after the issue. I am attaching 

% journalctl -b -1 > boot1.txt

% journalctl -b -2 > boot2.txt
% journalctl -b -3 > boot3.txt
% journalctl -b -4 > boot4.txt
% journalctl -b -5 > boot5.txt

Just to be clear it is happening for at least just 2-3months (with previous version as well).

[ahmmad.ismail]

Sorry for spamming. I am new and do not know how to attach files. If I copy paste the file content and just post it. Moreover, I could not edit.

The whole system freeze is suspicious, may be out-of-memory or desktop/window manager/kernel crash.

I want to add that I have 32GB ram. If I open ~300 tabs in firefox in normal mode (not incognito mode), there is no problem.

This looks interesting and it's related to teamviewerd. The other logs does not contain any abrupt shutdown info.

From the diagnosis, likely not caused by Firefox itself.
