Hey so I've been having this issue where the Ticketmaster website (no matter which country) does not work on Firefox... It just shows that message in the image.
I've tried disabling my VPN, uBlockOrigin, Privacy Badger, Firefox's Enhanced Tracking Protection, but no avail. I had to use G**gl* Chr*m* the other day to buy a ticket. Weird enough, I just tried using Firefox in my work laptop and the site worked without issues, even with uBlockOrigin and Privacy Badger enabled.
Any tips that might solve this without resetting my whole browser to default settings? Thanks!
Also, you can try to launch it in troubleshooting mode. It disables extensions and custom settings.
