As far as I know, mozilla firefox creates a directory in home folder/local settings in case of windows. So when I try to run firefox 4 rc and firefox 3.x only one is launched, is it possible to have these two run side bye side?

In some cases you may need to pass -no-remote
in order to inhibit Firefox from opening another window from the existing instance instead of starting a new instance.
Yes, I do it. You can use the same profile (it will disable extensions, etc. if they're incompatible), or create multiple profiles. See this article and the wiki.

@Kumar, what doesn't work? Did you just try just running
firefox -ProfileManager
(or firefox-4.0, whatever the case may be) and choosing? If that works, you can then setup a shortcut. Mar 28, 2011 at 19:14 -
For ff3.6 and ff4, I used
firefox -ProfileManager
, created profiles for both in totally separate folders, one by one, then launched FF4 & tried launching ff3, didnt work, note that in when I launched ff I used profile manager param, then I tried using-no-remote
, didnt work either, now the issue is ff3.6 is set as my primary browser and I have tried all possible things to set chrome as my browser but it wont work either :(– KumarMar 29, 2011 at 3:40 -
@Kumar, you may need both ProfileManager and
-no-remote
. Did you try them in combination? As far the default browser, try these instructions. Mar 29, 2011 at 15:41
Yes; it requires two things though.
- Create a new profile like Matthew says
- Pass
-no-remote
tofirefox
OR setMOZ_NO_REMOTE=1
(deprecated)

Have you tried it? I am on Debian and have tried it but it doesn't work, may be am missing something...– KumarMar 24, 2011 at 3:33
In answer to your question, Yes. Even if Firefox will only let you run one instance at a time, irrespective of the version number, then you can still get around it with third-party software which allows you to run more than one instance.
Try Sandboxie.
