Downgrading to FireFox 3.6

There is a FireFox Add-On that I’d like to play with, but it apparently only works with up to FireFox 3.6 and I’m on v19!!

I am on OS-X Snow Leopard.

Is there a way to either have two instances of FF running on my MacBook, or downgrade to FF3.6 for a while and then upgrade back to FF 19 without losing any of my Settings, Bookmarks, etc??

Sincerely,

Debbie

You can have as many versions of Firefox installed at the same time as you like.

From what I have read, that is not true for Macs…

A few results from a search of Google for how to install multiple copies of Firefox on a Mac:

Certainly looks like it is possible to install more than one version of Firefox on a Mac

Okay, I stand corrected!

Thanks,

You can save those if you want. Just do a Google search for where they are stored, then back up the folders that contain preferences etc.

Mind you, if something is that out of date, I figure it’s time to let it go.

All the same, you may be able to do what you want with the Mozilla collection. (I’m not sure if it can handle add-ons, but worth a look, anyhow.)
