Firefox should automatically stop re-directions and also notify you. Will have a small strip across the top and then in big blue letters on the page tell you is going to this site and asks if you want to allow it.

I would think you would have to reverse your changes as it may be interfering in how Firefox works now, or create a new profile to see. also https://support.mozilla.org/en-US/kb/how-does-phishing-and-malware-protection-work?as=u&utm_source=inproduct but can not find the auto redirect block. Just know it comes up for me all the time.

That old accessibility feature -- intended to avoid disruption for the users of screen readers -- is not comprehensive and is easily bypassed by sites that want to bypass it. It also has the annoying habit of stopping desirable redirects. You probably need an add-on to handle this problem.

Thanks, but do you know of an addon that can do this? Refresh Blocker, which I still use on my esr, has not (can not be) ported to Quantum.

I'm not familiar with any add-ons related to redirects.
