I'm using Ubuntu 20.04 LTS. Firefox is the only browser installed here, so it's the only one I use. The processes list doesn't contain a firefox process (both the system monitor and terminal). It's that normal or it's a signal there is something wrong with the system?
With help of @mivk.
The command below shows the firefox processes in the terminal:
ps ax | grep -i firefox. The processes appear as
/usr/lib/firefox/firefox in Ubuntu 20.04.3 LTS.
And this shows the processes in the System Monitor:
In System Monitor, it will show as "Web Content" and others under the "Process Name" column. You have to enable the "Command Line" column to see "firefox".
