Run several Iceweasel/Firefox instances independently

Create new profile

To separate two or more Iceweasel/Firefox instances which its sets of properties, cache, cookies and so on you can create a new profile by starting Iceweasel/Firefox from commandline:

$ iceweasel -p -no-remote

Run Iceweasel/Firefox in its own scope

To start Iceweasel/Firefox not with the default profile but with your created profile instead:

$ iceweasel -p [profile name] -no-remote

The -no-remote option is needed so that the new started Iceweasel/Firefox won't be connected to a running Iceweasel/Firefox instance.

Note: Don't run the same Iceweasel/Firefox profile with the -no-remote option twice cause this may result in profile data inconsistence. To be sure that several instances of the same profile sync their data properly they must run without -no-remote but via the New Window option within the Iceweasel/Firefox menu instead.
