I upgraded my Ubuntu system to 26.04 yesterday and re-installed Firefox, now running Firefox 157 from snap.

The Firefox Rescuetime extension is no longer working properly. I uninstalled it and re-installed it, but when I try to authenticate with Rescuetime, the extension is pointing to `dev.rescuetime.com`, _not_ Rescuetime production, and my production credentials don’t work.

Is anyone else experiencing this problem?

I’m technical and happy to provide further diagnostics.
