And to have same facility with firefox, you can use Edskes Software Mozilla Firefox Collection
Another way to have multiple firefox versions is:
- Install all different versions that you want to have in different 'Program Files' and 'Start Menu' folders.
- Create a separate firefox profile for each version.
- Right click shortcut icon of each version > Properties > In “Target” textbox; append “-P oldfirefox -no-remote” (without quotes). 'oldfirefox' is the profile name you created in step 2.
- Remember, you have to append this command at all places (Desktop shortcut icon, Start Menus entry, Quick Launch icon) separately.
