Downloaded Firefox 5 onto Mac OS 10.4 and it won't run, how do I revert to to Firefox 3.1 which I was using before?

As this is not my own computer and shouldn't have tried to update from Firefox 3.1 to 5, I did and now it won't work. This MiniMac has OS 10.4.11 on it and I would just like to go back to 3.1 without having to download from a third party site. Thanks.

There is no Firefox 3.1 as perhaps you mean 3.6.18

as of Firefox 4.0 it is Mac OSX 10.5 or newer and a Intel that is required.

Firefox 3.6.18 can be found at http://www.mozilla.com/en-US/firefox/all-older.html as just look in the Mac section and pick the language you want.

Thanks... I had just gone to that page but didn't look closely enough. Now I know.
