How to fix problem that I have two different versions of Firefox on one laptop?
After moving to a new Windows 11 laptop and copying programs from the old laptop with PCmover, I seem to have two versions of Firefox that look different. If I start Firefox from the Start, Programs, it looks like it did on my old laptop. It has the correct extensions and all my correct settings and bookmarks. It is Firefox Developers edition 1.45.0b9, which I’ve used for years. I want this.
But there seems to be a new, second version that looks different and does not show my extensions or bookmarks. It is Firefox Windows MSIX 1.0. This is the version that now acts as my default browser when I click on a link in an email. I don’t want this but I’m not sure how to fix this problem.
In setting up default apps in Windows, it only gives me one Firefox choice. I have no way to choose between the two shown above.
How can I fix this?

That sounds like the extra one was installed via Microsoft Store.
Unfortunately Windows can't really clean up after itself so it might not be able to tell the different apps apart. In your Settings > Apps > Installed apps you might be able to find and uninstall Firefox from there, however it might remove both. (Back up your profile folders before removing anything to be on the safe side.)
So if it removes both, you'd download the normal version from firefox.com, and that one has its profile in the location your original one is stored now, so that's the version you want.
