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!
I missed that part about Firefox at work working. Then yes, it is less likely compatibility issue. Needs debugging.
If you already tried disabling all addons (and then cleaning website data + refreshing page with ctrl+shift+r), it could be some setting in browser.
If you go to about:config (type, not copy-paste) in browser, it will open many configuration flags. Flags with bold font have non-default value. If flag description sounds like it could be related, try resetting it.
As a last resort you may try Firefox Beta or Nightly :)
Thanks for the pointers!
For now, changing the user-agent as suggested in another comment did the trick. Later I will try to debug with your steps and see if I can track down the root cause.
If changing user-agent worked (all it does is changing reported browser and version used to the website when loading, it's a header in http request), then it's not a problem with the browser.
Since they are mentioning bots, this is probably what changed. Some combination of IP address, user-agent and whatever else they have access to triggered anti-bot protection. I would assume ticket-selling website this big fights bots on daily basis, you just happened to be collateral :)
