ฟอรั่มสนับสนุนของ Firefox

Since the last FF update (115.5esr, Windows 8.1 Pro) I keep getting the following error message when I try to access one particular website:

The page isn’t redirecting properly An error occurred during a connection to www.doordash.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I have tried virtually all the solutions suggested online. I have cleared my cache, deleted cookies and site data, and I have tried to access the site using Troubleshooting mode, all to no avail. I contacted support for the particular website and they have no difficulty accessing the site with FF.

I can access the site in question with the Chrome browser, so the issue would appear to lie with Mozilla. I use this particular site frequently and would much prefer to continue to access it using it with FF, as I have done for over a year. I just installed Chrome on my Windows 8.1 Pro PC solely for the purposes of accessing this one website.

Help in resolving this issue would be greatly appreciated.

Every time I allow Mozilla to update Firefox, smooth scrolling ceases to work. Think maybe I've now had enough. Chrome can't be any worse than this.
