Portable double installation

I have been using a very old version of firefox on my desktop. Now I want to update it, but to somehow keep an installation of a pre-webextension version. IIRC two different installations can't live within the same Windows, so I'm looking for a portable installation of the old version. (Running a second instance of the same installation is no help).

The problem is that I already have an updated portable app on my usb stick. I am wondering, if I save an old, portable firefox (on a separate folder) on the same usb stick that already has a portable firefox installation, will it cause any trouble to either?

Yes, you can have more than one Portable Firefox version or installation on a USB stick. You can also have Portable Firefox 'installed' on your hard drive, and it won't affect an older Release version of Firefox that is already installed on that computer. Portable installs completely separate from the official versions of Firefox.

What version of Firefox are you using?

WARNING ! ! The newer Quantum Firefox versions do not support older add-on programs.

Not as old as I thought. Some update sneaked in. v 56.0
