Hi, I'm using Firefox with gnome (linux). Version of Firefox is 56.0.2. For some reason I was checking Firefox process on the command line (with "ps -elf | grep firefox"). Everytime I do that I get the process of Firefox with a very lengthy command line. There seems to be many options some of which using weird looking characters. I was wondering if this is normal and if so where I could find explaining about these options. One of those options is "-stringPrefs". Searching for "-stringPrefs" with google doesn't give any result. I've looked also at one support page listing the command line options of firefox (https://developer.mozilla.org/fr/docs/Mozilla/Command_Line_Options) but I couldn't find anything related to "-stringPrefs" or "string" or "Prefs". What are these options? Where could I find out?

Thanks indeed this seems to be options passed in string form to firefox. I'm still trying to understand what are the specific preferences I have in my command line.
