Some web-based applications that I use will not work properly with Firefox 3, but will work with Firefox 2. Can I have both versions of Firefox on my iMac and select between them, or will they interfere with each other? Would it help if I put one on my external hard drive and run it from there (if that is possible)?

    you can have two versions of FF but you can't run them both from the same account as they will interfere with each other.
    You can make a new user account and run FF3 from your main account and FF2 from the new account.

    no, that would make no difference at all.

    FireFox allows multiple user profiles to be configured for use within a single OS X account. If separate profiles are created for versions 2 and 3 of FireFox, it should be possible to use both versions at the same time.

    To set up profiles initially, try launching "/Applications" > "Utilities" > "Terminal.app" and enter a command of the form below, substituting the appropriate path to either FireFox version:<pre>
    /path/to/Firefox.app/Contents/MacOS/firefox -ProfileManager</pre>

    Once the profiles are set up, it won't be necessary to use the command line again, as a dialogue will appear allowing a profile to be selected when either FireFox version is launched.
