e.g. copying x-firefox installation to a different directory, changing X-Firefox.ini by uncommenting MOZ_NO_REMOTE=1. Another time, I made a new profile for the 2nd copy and changed it in X-Firefox.ini too....
Furthermore I tried to use the parameter -no-remote in X-Firefox.ini...
etc...

But everytime, I receive the notice: "firefox is already running", or in English or in Italian

using the -no-remote with firefox.exe in the bin\firefox directory works well.
so it must be possible, only there seems a configuration problem with the x-version

Being confused: who had been able to run multiple instances of x-firefox & what was the configuration?

Many thanks,

Apologies
Anyway, it is quite easy to solve your issue:
in the "X-Firefox.ini" file You need to modify only the following parameter:

MultipleIstances=true

You can find it almost at the end of the ini file, in [Options]

IMPORTANT NOTE:
Be careful! Be sure to avoid starting at the same time an installed Firefox session and a X-Firefox session in two different istances
Enabling MULTIPLE ISTANCES, the risk is to loose your original profile data in any INSTALLED firefox present on your PC.
If You have ONLY X-Firefox on your PC, You are free of risks!

PS:
I don't remember if unidentiting
MOZ_NO_REMOTE=1
is still working...
Theoretically it'will work, but I don't use it anymore.

Have a nice week-end]]> Taf Fri, 13 Jun 2014 08:47:06 +0200 http://www.winpenpack.com/main/e107_plugins/forum/forum_viewtopic.php?58741 Re: running multiple instances of x-firefox (29.0.1) http://www.winpenpack.com/main/e107_plugins/forum/forum_viewtopic.php?58741
Thanks for your reply.
I tried this out. Using another copy of same x-firefox or launching it again, opens a new window, but doesn't launch a second executable with its own cache etc but only opens a new window.

I did something wrong?]]> Stijn Fri, 13 Jun 2014 16:43:09 +0200 http://www.winpenpack.com/main/e107_plugins/forum/forum_viewtopic.php?58741 Re: running multiple instances of x-firefox (29.0.1) http://www.winpenpack.com/main/e107_plugins/forum/forum_viewtopic.php?58741
To have a second executable with its own cache etc. (as per your request) you need to enable also:
MOZ_NO_REMOTE=1

uncommenting it
at least in one of 2 different X-firefox.

I made some test right now:

I have a X-Firefox with 24.6.0 ESR release and another one with latest version (30.0)
with different settings and different extensions.
Unsing:
multipleIstances=true in both
and
MOZ_NO_REMOTE=1
in one of them, I'm able to run different executablen in same time

hope this helps]]> Taf Fri, 13 Jun 2014 17:32:22 +0200 http://www.winpenpack.com/main/e107_plugins/forum/forum_viewtopic.php?58741 Re: running multiple instances of x-firefox (29.0.1) http://www.winpenpack.com/main/e107_plugins/forum/forum_viewtopic.php?58741
Thanks a lot. It works.

I did the test by running 3x firefox:
1) multipleIstances=true in all x-firefox.ini
and
2) MOZ_NO_REMOTE=1 in all but one

Many thanks,

Stijn
