Firefox won't stop loading

Yesterday I noticed Firefox will load, then almost immediately reload and it keeps up in a continuous loop. If I use a Canadian VPN it works fine. My home page is Yahoo, which is reloading. I have a Mac Mini M4 using Tahoe 26.6.2. If I use Safari, there is no problem. My Firefox version is up to date with 154.0.1. I tried shutting totally down and restarting with no difference. If I go to another site, there is no problem.
