Well, yes, if your RAM is full and cannot be outsourced to swap storage
then undesirable things happen.

If you see in dmesg output
  [...] BERT: Error records from previous boot:
then maybe this is hardware related too.

But if firefox is just eating up your memory, then only more RAM or more
swap storage can help.
For a quick test, you could create a swap file on disk and try whether
your system gets more endurance.
See e.g.
  https://linuxize.com/post/create-a-linux-swap-file/

If not by some colorful system monitor i would watch the load on RAM
and swap by periodically executing command
  free -h
and ignoring all its columns except the first two: "total" and "used".


But as one can see from my recent posts, i am not an experienced sysadmin
who knows the most thorough hardware tests.


Have a nice day :)
