''[Locked as a duplicate of https://support.mozilla.org/en-US/questions/1295169. Please follow up there, thanks.]'' For some reason, I'm now completely unable to log in to iCloud through firefox, I'm presented with the following error message upon the site loading (screenshot below). I've tried restarting the browser in safe mode but it didn't solve the problem, not sure what's going on. Also after a few seconds, the page spits out an iCloud connection error, screenshot again, posted below. See also: I've just noticed that the troubleshooting information section of this form is also completely broken for me, the "Share Data" button doesn't work, and the link to try manual steps just scrolls me to the top of the page, nothing else happens.
