For some testing I need to run two instance of different firefox versions at the same time. But with default setting it is not possible.

It can be possible with firefox profilemanager

On my Ubuntu box I have two versions of Firefox one is beta another one is stable.

I can run stable version via firefox command, to run beta version I issue firefox-4.0 command.

So the trick is creating a profile for another version firefox, in my case Beta Firefox

To create profile run

firefox-4.0 -P --no-remote

Click on Create Profile

Click Next button to proceed.

In Enter new profile name: insert profile name as per your need. I choose FirefoxBeta, and click on Finish button

Creating Custom Launcher
Here I am using GNOME. To create custom launcher, right click in application launcher pannel, choose add to panel

Select Custom Application Launcher, and click Add button.

In Name type Firefox Beta. In command type firefox-4.0 -P FirefoxBeta –no-remote, and click on OK button.

That’s it, now you can run two different version of Firefox at the same time. See below screenshot
