I have Firefox set to clear everything when I close the browser.

It's time to just push the button...

Did it make a difference? Did you try with Firefox in Troubleshoot Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf

You can also try Refreshing Firefox. https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings

It is possible that your firewall or other security software blocks or restricts Firefox after detecting that Firefox updated. Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full access for all Firefox processes.

Boot windows to safe mode and see if Firefox loads any faster.
