Two firefox.exe processes

Hello there.

I noticed earlier a slight change in firefox behaviour, slight delay when allowing scripts in a website (through the NoScript plug-in.)

I couldn't work out what was causing it, I thought it was possibly just an update to NoScript itself introducing an error but then I stumbled upon two firefox.exe processes open in Task Manager.

Both of them open when I open firefox itself, one is just the base Firefox location in the command line, while the other has a long argument. The long argument is as follows: "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -contentproc --channel="(long number here)" -greomni "C:\Program Files(x86)\Mozilla Firefox\omni.ja" -appomni "C:\Program Files (x86)\Mozilla Firefox\browser\omni.ja" -appdir "C:\Program Files (x"

Is this normal behaviour? I tried creating a new profile as well as running in safe mode but both processes still open. I have run malware scans and they have come back clean.

Thank you in advance.

Edit: Reading up a bit about the new firefox changes. Could this be from Electrolysis? I checked about:support and it is enabled for me.

Aha, it would seem that is the reason then.

Thank you very much!
