Hi, I have been using an extension that helps with my school's website for years and now for some reason it has been taken off the firefox store. It's still up on chrome and edge and all of the Dev's other add-ons are still up, its only this one on firefox. I emailed the dev and he sent me the zip file and I've been having to install it as a temporary add-on with the .json file every time i open firefox and its getting really annoying after a year of doing this. How can I just install it permenantly?

You can consider to use the Firefox Developer Edition as that supports xpinstall.signatures.required.

I have that preference marked false in my (regular) version of Firefox.

Yes, you can modify that pref, but does it work if you test this with an extension and edit the XPI file or remove the META-INF folder.
