I have two instances of firefox running under separate profiles:
$ firefox -P default &
...
$ firefox -no-remote -P second &
Now I can open a new tab from the command line with:
$ firefox -new-tab http://unix.stackexchange.com
But how do I open a new tab in the second profile?
This:
$ firefox -P second -new-tab http://unix.stackexchange.com
opens a tab in the default profile, while:
$ firefox -no-remote -P second -new-tab http://unix.stackexchange.com
complains that there is already an instance running under that profile.

It works now with
firefox
29.0 on Linux:To open a second
firefox
instance with a different profile:firefox -P second -new-instance
To open a new tab in the second instance of
firefox
, which os already running:firefox -P second -remote "openurl(http://example.com,new-tab)"
See Bug 716110 - split -new-instance flag out of existing -no-remote flag for additional hints (eg: post of Hayo).
As explained in the comments on this bug report, what is missing is a command that can be used for opening the first window and the second tab in the same way:
That could be done with a script along the lines of this (
firefox-profile-instance
):Now, while a firefox with the default profile is already running,
the first run of this starts a new browser with profile "second":
firefox-profile-instance second "http://example.com"
and running the same again opens a second tab in the same browser:
firefox-profile-instance second "http://example.com"
