I unfortunately switched back to Chrome last week after having used Firefox for years due to not being able to use sites I frequent. I constantly ran into issues with Heroku, GCP (go figure), and a few financial sites I'd log into regularly.

I know it’s mentioned elsewhere, but this does it for me:

* Try the same site in a private window (assuming plugins are disabled when in private)

* If on dev or nightly, try those sites on the regular release.

I haven’t bumped into anything in GCP that fails to work on ff, though likely don’t use the console as extensively.

What do those sites say about the problem when you report the error to them? Do any of them acknowledge their error?

did you check if you have any funky plugins enabled?
