421651 - Cannot run different profiles or ProfileManager once firefox is running

Status: RESOLVED DUPLICATE of bug 308076

(Toolkit :: Startup and Profile System, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.12) Gecko/20080207 Ubuntu/7.10 (gutsy) Firefox/2.0.0.12
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.12) Gecko/20080207 Ubuntu/7.10 (gutsy) Firefox/2.0.0.12

Once I already have a firefox session running (say profile 'prof1' by running firefox -P prof1) I cannot get firefox to run with a different profile (say profile 'prof2' by running firefox -P prof2) or to even bring up the ProfileManager (by running firefox -ProfileManager). Instead when I run it the second time I get a second window under the first profile. This is using brand new profiles without any addons or themes installed. The switches seem to be ignored once firefox is active. If there are no instances of firefox, the Profile Manager (or the correct profile passed with -P) comes up. I ran strace but the output was pretty similar whether an instance was running or not (just PIDs and memory locations were different). I realize this may not be happening to everyone or it would have been caught by now so let me know if you want further information to resolve this.

Here's my profiles.ini used for testing (created by ProfileManager):

[General]
StartWithLastProfile=1

[Profile0]
Name=prof1
IsRelative=1
Path=ypi91dtq.prof1
Default=1

[Profile1]
Name=prof2
IsRelative=1
Path=h6ad9mwy.prof2

Reproducible: Always

Steps to Reproduce:
1. Run firefox -P prof1
2. Run firefox -P prof2
Actual Results:  
Get a window of prof1 in both cases

Expected Results:  
Should get a window of prof1 the first time, and prof2 the second time

This a dup. The behavior is by design, use -no-remote

When did this behavior change? It was working when I was on Kubuntu 7.04 (same Firefox version). Also -no-remote doesn't show up under firefox --help (where it lists -P option).
