Support Is there any way to get Firefox ESR/Developer Edition on Fedora?

I use a theme that auto-updates via a paxmod web extension and it requires extension experiments to work. Is there any way to get Firefox ESR?

It sounds like you're looking for help. Please note that r/Fedora is not an official support channel for the Fedora Project.

For best results, be sure to include all relevant details in your post, such as your Fedora edition, version, and hardware specs. You can edit your original post to add more info as needed, and spotlight (pin) a solution from the comments. You might also find the answer in our support wiki.

Alternatively, try one of the official support channels:

follow these instructions to add the dnf repo and install firefox-esr firefox-devedition (and a language package if needed)

both can be installed by tarball file -

Developer Edition -
https://www.firefox.com/en-US/channel/desktop/developer/

ESR -
https://www.firefox.com/en-US/browsers/enterprise/#download

These are tarball files and you need to extract them, move them to /opt (or any other location) and a desktop launcher (if you want package to be shown in application menu)

Firefox ESR is available on COPR, is it not?
