Default Browser: Firefox 7 Operating System: Windows 7 (64bit)

I want to install multiple versions of Firefox (for testing purposes).

I currently have Firefox 7 installed (two different profiles - one for casual use, one for web dev).

  • "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -P casual -no-remote
  • "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -P webdev -no-remote

I located previous versions of Firefox here:

I installed Firefox 6 with a third profile

  • "F:\Programs\Firefox 6\firefox.exe" -P FireFox6 -no-remote

The problem is that every time I attempt to install a previous version, Firefox begins to update itself (to version 7.0.1). Ideally, I would like the most recent version auto-update and have all of the previous versions stay on the version that I install.

How do I install Firefox in Windows 7 (64bit) with multiple versions with updating?

Change the setting in Options, it is saved per-profile, so disable updating in old version profiles, and keep enabled in newest version profile.

Firefox update
