I have a website that is most compatible with a specific version of Firefox and I want to always open it in it's own instance with that version but I want all other shortcuts to open in the newest version. I have tried -new-instance but if either of them is open before the other it automatically opens as the version that was already open.

Ex. 1

1. Use old version shortcut with -new-instance and it opens the old version

2. Use new version shortcut with -new-instance and it opens in a new instance with old version

Ex. 2

1. Use new version shortcut with -new-instance and it opens with new version

2. Use old version shortcut with -new-instance and it opens with new version

You can install as many versions of Firefox that you want. However;

Switch to manual and place each version in its own folder.

The Last Firefox you install will be labeled as the default program.
