Since I develop web applications, I feel obligated to make sure my applications work in all sorts of browsers. (Hell I even still check IE 6 from time to time…). I don’t really test Chrome our Safari that much though since most of my users of my major applications are IE and/or FF users. Anyhow, Firefox is being a pain with all these 6 week releases and I didn’t want to deal with it so I stopped testing past 4.0. Today I opened up my browser and it was asking for me to download Firefox 7.0! *Sigh* Ok Firefox, you win:
I am now running IE 6, IE 7, IE 9 (has compatibly modes for IE 7,8,9) and Firefox 3.6, 4, 6 and 7. (I couldn’t find the download for Firefox 5. Apparently it had a lot of security issues so they probably don’t want you to have it.) How did I do this? Easy, you just create a new profile for each Firefox and install each version in a separate location. Assuming you already have one version of Firefox installed:
- Download all of the versions that you want to work with
- Install each version into a separate location
- Do a custom install to do this.
- Make sure that you do not check “open after install”
- Create a new profile to use for each version
- Create Desktop Shortcuts to run the different versions of Firefox
- Right click on Desktop and click New -> Shortcut
- For the path enter the location of an installed version of Firefox and open it with the correct profile name you created
- “C:Program FilesMozilla Firefox 4firefox.exe” -P Firefox4
- Repeat previous steps for each version you want.
And you get:
