Firefox profiles aren't very useful - all instances open with same one

I am running Linux: LMDE Cinnamon Edition - 64 bit I am using firefox version Mozilla Firefox 31.0

I wish to have two instances of FF running. One with my standard, personal settings and a second instance that ONLY connects to Facebook and will stop data leaking between the two. I can acheive this by opening Facebook in another browser (e.g. Chrome or Opera). I checked the ProfileManager under Firefox and created a second profile called "FB". I can run firefox -p FB and it will open an instance of FF with none of my personal settings available - that's what I was hoping for. However, if I run a second instance of FF - for example from the command line as firefox -p default it loads with the same profile as the first instance I opened, not the new profile as specified in the command.

I can only select the profile if there are no prior firefox instances running under my user-id. The first instance defines which profile is used for all subsequent executions - no matter which profile I specify on the command line. Even running firefox -ProfileManager will start with the first-specified profile, not the profile manager.

Hello,

If you want to run multiple instances of Firefox, you need to add a -no-remote parameter to the command.

For example:

  • firefox -P -no-remote

Thank you very much. I did see that option in "firefox -help" but it says: Do not accept or send remote commands; implies -new-instance

which didn't mean anything to me.

regards from a satisfied user.

Just make sure you do not use the -no-remote switch with the default Profile and you only need it for the second instance.

The way you were trying to do it has not worked ever since version 1.0 and earlier Releases then.
