I have used Firefox successfully for years and never had any significant problems. Now, (version 90.0.2) all of a sudden I'm getting severe speed degradation using internet web pages. My normal speed with comcast is around 170 mbps but now getting less than 50 mbps with Firefox. Oddly, I am getting normal speed when using the Chrome browser. Comcast has run their checks and found no problems.

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?
