We're missing an important verb here. If that's what you use to launch firefox, yes it looks a bit odd, but you'd know why you are doing it.

I presume this must be some command line you saw somewhere, but where did you see it? Is this output of some parsing of /proc/*/cmdline? Or where did this come from? What are you actually asking?

It looks like parameters incluing intPrefs are used by firefox to pass information to other process instances that it starts - so I might not find it odd if that is the command line used within firefox to spawn new (sub)processes. But again that depends on where you go this command line: is it a child process of the main firefox thread?

I see a similar Firefox process all the time (in htop), it is the child process of another firefox process and started appearing since the last Firefox release -- I assume this is normal for Firefox e10s then.

I wouldn't worry about it.

My guess is it's probably related to the transition to multi process firefox is doing. See http://www.phoronix.com/scan.php?page=n … 4-Released

From what I have observed it would only show up after loading some page with media, like HTML5 / Flash video.
