Extremely slow

I am running the latest update for Firefox (143.0 (64 BIT) on a Windows 10 Dell laptop. Since the update on August 28th (prior update), my browser has been extremely slow, even with only one tab open. Task manager shows 95% memory usage after 15 minutes of browsing, and I have to end task on Firefox, then reopen the browser. I have run my Webroot antivirus and Malware Bytes, and my laptop is coming up clean.

I am not fond of Microsoft Edge, but I wanted to see how it performed. I have no issues with speed, so I can only guess that this is a Firefox issue.

Are there any known issues with the August 28th update?
