Bug 1923500 may not have resolved all online banking issues
I recently started having a problem with my banking website. Before I could investigate or report it, Mozilla released a bug fix 1923500 "Firefox 131 Enhanced Tracking Protection major breakage of multiple banks Bill Pay services" I have updated to Firefox 131 however, there may still be a problem, however before I report it I'd like to verify if it's simply that their link is broken. Let me explain: On my bank's website there is "Payment Inquiry" link with this link "https://paybills.MyBankName.com/imm/Auth/SLO/4661?ReturnUrl="
What happens is that it sends me back to the login screen, I navigate to the Payment Inquiry again, click the link... rinse and repeat... in an endless loop. I suspect that the URL is malformed because there is nothing following the "=" sign. I would expect something to follow the equal sign. Is this indeed a bad URL? Should I pursue with my bank? I only ask because is seemed more than a coincidence that this occurred near the same time as bug fix 1923500.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.
- switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click "Refresh Firefox" in the Troubleshoot Mode start window

Reboot the computer into Windows Safe Mode with network support to see if that has effect.
Hey FoxTech, I was the one who filed that bug. I would go ahead and report that url issue to your bank and ask them to escalate it as you can't pay your bills. But as a different test, you could temporarily install Edge, or if it's already installed just open it and login to your bank. Then pay close attention to the "Payment Inquiry" link. Right-click it and see if you can copy the url. Sometimes they block this ability if this link is using javascript.
But even if they hide the url from being right-click, copied you should be able to see the full url in the url bar. See if anything has been added to the "ReturnUrl=" part. If the url quickly redirects to another page so you can't see what was added, you can click in the url bar and use the Undo keyboard shortcut Ctrl+Z. That will show you the previous url you wanted to see. You can keep using the Ctrl+Z shortcut to go back to more previous urls if extra urls were visited after clicking that Payment Inquiry link.
The other idea you can try if the above test doesn't give you the "ReturnUrl=" part, is to set your Tracking Protection to Standard. If its set to Custom or Strict that could be causing the endless loop you're seeing: https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop#w_adjust-your-global-enhanced-tracking-protection-settings
