Run Firefox 2 and 3 simultaneously
Despite the vast improvements in Firefox 3, I've still been using Firefox 2 because of the instability of Firebug 1.2 (beta versions). The final Firebug 1.2 version was released recently, and many of the issues have been resolved, however, I thought I'd post the steps I took to run both Firefox versions together:
If you already have one version installed, just install the other version, making sure to choose the Custom installation option. This will allow you to install the files into a different directory.
For example, if you already have Firefox 3 installed in
C:\Program Files\Mozilla Firefox, install Firefox 2 in
C:\Program Files\Mozilla Firefox 2. The rest of this post assumes that you are installing Firefox 2...modify as necessary.
From the command line, run the Profile Manager to manage your Firefox profiles:
"C:\Program Files\Mozilla Firefox 2\firefox.exe" -profilemanager
Create a new Profile,
firefox2 for example, and then exit the Profile Manager.
Update Firefox Shortcuts
Target value on your shortcuts to Firefox. Right-click on the short-cut and select
For the Firefox 2 shortcut, on the
Shortcut tab, enter:
"C:\Program Files\Mozilla Firefox 2\firefox.exe" -no-remote -p firefox2
Do the same for the Firefox 3 shortcut, with the following:
"C:\Program Files\Mozilla Firefox\firefox.exe" -no-remote -p default
Install Firebug 1.05 for Firefox 2. You should now be able to run both Firefox 2 and 3 simultaneously. If you already have Firefox 2 are installing Firefox 3, just change the paths/profile names mentioned above to fit your situation.
Caution: If you already have one version installed, use the Firefox Profile associated with it, otherwise you might loose your settings.
