Firefox Issues

Using Fedora 32 with default Firefox 80.0.1 browser. Lately Firefox has been somewhat unreliable in that it occasionally won't open a page after entering a URL. A few days ago, I was trying to pay for an order via Paypal and Firefox failed to open the Paypal login page as it normally does. It did the same a few weeks earlier. I have used Firefox for years with no issues. This is new. I don't have these issues with Chromium or Chrome. I've started depending on either of these for anything serious.
Does anyone else have similar issues? Is there a solution?
