On what sites/links is this happening? Is this with all websites/pages, some, a few?

Redirects could be a cookie problem.

Many site issues can be caused by corrupt cookies or cache.

If there is still a problem,

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

While you are in Troubleshoot(Safe) mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

This only happens on one site so far. It doesn't happen if I log into the site using another browser, and it never happened with I logged into the site before the update yesterday to 96.0.3. I think it must be related to the update.

I have Firefox set to erase history after each logout. But I tried everything you suggested. I deleted cookies (there were none) and cleared the cache (which was not empty but it is now). I started Firefox in safe mode but the problem is still there.

Thanks for trying to help me with this.

Delete browsing, search and download history on Firefox {web link}

Remove a single website from your history {web link}

Open the History Manager <Control> (Mac=<Command>) <Shift> H. In the search bar, enter the name of the site. Right-click on one of the listings and select Forget About This Site. This should remove all information, including any site settings And Passwords.

If the problem still happens in troubleshoot mode and neither of those clearing methods work, there are these methods.

1. An add-on called Block Site (which I haven't used); 2. You can add the site to uBlock Origin (another add-on); 3. You can add the site to your hosts file. Search for hosts file on Windows.

Thanks for the suggestions, but they didn't work or were too intrusive (the add-ons). Interesting to learn about host files, which appear to be able to block a site but don't allow me to stay on a site attempting a redirect.

I would have thought Firefox would include a feature to block sites and override redirects to them. Anyway, I finally solved the problem by blocking the site in my antivirus program. This does just what I wanted. Stupid of me not to think of it sooner.
