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?

    Have you tried ps ax | grep -i firefox or similar? For me, it does show several processes as /usr/lib/firefox/firefox. in Ubuntu 20.04.3 LTS.

  • @mivk I tried ps | grep -i firefox. Looking at the command you have mentioned, looks like I misused the command. Now it shows several processes as /usr/lib/firefox/firefox, like yours. Still, nothing appear at the system monitor. Do you think it's normal?

  • 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".

  • @mivk I have enabled the "Command Line" column and now I can see firefox's processes. All right now. Thanks for the help.

  • @Ezau if you have a solution, whether solved via comments or otherwise, it's suggested that you would take your solution and post it as an answer to your own post, and then accept your own answer. (There's, otherwise, no reason to 'close' the question as you already have an answer)

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".
