Lately, during our development process, we came across a situation wherein we had to test our application designs on Mozilla Firefox 1.5 and 2.0. This was causing a lot of problems as we had to keep checking on multiple machines, because each machine had only one version either 1.5 or 2.0.

I read many posts on how to install multiple versions of Firefox. But there as a catch, I could run only one instance at a time. That means, if I open a window for Firefox 1.5, I can’t open another window with Firefox 2.0

Below are the steps I followed with inputs from Hiveminds

1. Download both the versions of Mozila Firefox (1.5/2.0) into a seperate directory
2. Install both the versions into a seperate directory using the “Custom” option. For e.g. for 1.5, I used
   C:\Program Files\Mozilla\Firefox1.5.x
   and for 2.0, I used
   C:\Program Files\Mozilla\Firefox2.0.x
3. After installing, open the profile manager. Go to Start > Run and paste the below code
   "C:\Program Files\Mozilla\Firefox2.0.x" -ProfileManager
4. Create two new profiles viz - “Firefox1.5.x” and “Firefox2.0.x”. Doesn’t matter which directory it saves in
5. Fire up your notepad and paste the following code for FF2.0
   @echo off
set MOZ_NO_REMOTE=1
start "" "C:\Program Files\Mozilla\Firefox2.0.x\firefox.exe" -P "Firefox2.0.x"
set MOZ_NO_REMOTE=0save it as "FF2.0.x.bat”

   paste the below code for FF1.5@echo off
set MOZ_NO_REMOTE=1
start "" "C:\Program Files\Mozilla\Firefox1.5.x\firefox.exe" -P "Firefox1.5.x"
set MOZ_NO_REMOTE=0

   save it as “FF1.5.x.bat“

6. Save both the files on your desktop and you are done! Execute both files one by one and see the magic unfold ;)
