Error: An unexpected error occurred

Helper app reports Error: An unexpected error occurred when attempting to run after installation.

The installer doesn't give any errors, and the manifest files are installed in the right directories. I'm not really sure what's wrong.

Try restarting the browser to see if it resolves the issue. If not, I think it is very likely related to flatpak / snap.

The principle is similar to video-downloadhelper: https://github.com/aclap-dev/video-downloadhelper/wiki/CoApp-not-recognized#ubuntu-and-flatpak--snap-based-systems

I have not tested the flatpak / snap environment yet. You may need the following command:

flatpak permission-set webextensions webext.fsa.app snap.firefox yes

Sorry that I couldn't get back earlier, I had installed the helper via the install.sh file, not through snap. The extension still throws the error after running the command and restarting Firefox.

For Firefox Snap, I think it is related to https://bugzilla.mozilla.org/show_bug.cgi?id=1661935 .
Have you tried the following command?

flatpak permission-set webextensions webext.fsa.app snap.firefox yes

If the issue is still not resolved, please try the following:

1. Ensure that fsa-host.py has execution permissions.
2. Open the browser console with Ctrl+Shift+J, click the 'Start' button on the extension page, and check if any errors are displayed in the console.
