Some Web Sites Running Slow on Firefox

Firefox runs some sites slows on one of my Windows 10 computers.

I'm running Firefox on 4 Windows PCs and 3 of the 4 work just fine using the same synced profile.

Fidelity.com and Amazon.com are 2 of the sites that are very slow to load. They will eventually load, but clicking on any links causes another slow load.

The same web sites are fast when I use MS Edge.

Troubleshooting steps I've taken (none of which have worked):

  • Refreshed Firefox
  • Created a new profile
  • Uninstalled Firefox leaving my old profile
  • Completely uninstalled Firefox and deleted my profile

Any thoughts on troubleshooting steps to take?

So you have a few Win 10 :) How about the PCs themselves, RAM, CPU, GPU etc. how are they coping individually. Have you compared them  ??

Two of the PCs are Windows 10. Two are Windows 11.

I don't see the problem with both Windows 11 PCs and one of the Windows 10 PCs. Only 1 Windows 10 PC Firefox installation is slow.

Any help is appreciated!
