I tried to look for the solution of how to run different Firefox versions such as firefox 3.6, 8, etc. But I could not really get two different firefox running. I went through mozilla’s documentation but that also didn’t help. After many hit and trial I found a way,so thought of sharing with others.

The steps are:

1) Create multiple profiles you want as mentioned in Mozilla documentation. For example:

2) Now make sure you have different versions of firefox installed in diffferent Destination Folders.

3) Create a shortcut for each firefox and set the “Target” in it’s properties. For example:

For Firefox 3.6 set Target to – “C:\Program Files (x86)\Mozilla Firefox\firefox.exe” -no-remote -p default

For Firefox 8 set Target to – “C:\Program Files (x86)\FirefoxLatest\firefox.exe” -no-remote -p firefoxLatestProfile

Now click on these shortcuts and you have different versions of Firefox running on Windows.
