I have been reinstalling an older version of firefox for months now. Decided yesterday to give this a go and see if I can make it work.

The add-ons that were most important multirow bookmarks and profile switcher are gone.

I found a work around for the multirow bookmarks using .css but I cannot fine away to run MULTIPLE profiles at the same time. The is seriously screwing with my workflow and I am ready to go back to an older version or firefox or look at other options.

I have tried the "firefox.exe -P" and it either opens the SAME profile again or simply does nothing.

Help. :(

^^ Please ignore what Pkshadow posted, as IMO that is all nonsensical for what you explained as wanting to do.



To get a 2nd Profile to launch while the first Profile is already running, you need to use the command line switch of -no -remote. That tells Firefox to ignore the already running firefox.exe process.

Works the same whether you want to run 2 (or more) Profiles with one Firefox version installation or you want to run multiple different versions / installations of Firefox, each with its own unique / separate Profile.

https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options - scroll down to -no-remote

Example of proper usage of that command. firefox -no-remote -P "Another Profile"

An overwhelming amount of information about this topic can be found here: http://forums.mozillazine.org/viewtopic.php?f=23&t=2821799 With the help and input from many other Firefox users I tried to cover all the variables when using multiple, simultaneous Profiles with Firefox. Mostly slanted toward testing Firefox pre-release builds while maintaining the latest Release version; but the information is there for almost all variables I have though of or used myself.

plus at the bottom of that posting there are links to the 4 earlier versions of that topic that I posted over the years going back to 2006

Install each program version of Firefox to a separate location/Partion or Hard Drive using custom install from a full version installer.

You can run any version along with Firefox Developer Edition as it has a compatibility mode.

Note it does share your bookmarks so always :

Or you can run 1 install and run a portable version

If a new Firefox Window is opening up instead of the ProfileManager dialog then Firefox was still running. You need to start Firefox with the ProfileManager when it is closed/exited.

No you do Not need to put the Firefox program folders in separate partitions or hard drives whether on Windows or Linux. If anything doing it your way may complicate things.

Thank you. You explained it perfectly and it works.

Is there anyway of incorporating this into a shortcut?
