I have been experiencing a very strange problem since the update to Firefox 89 (which has persisted with 90 and 91), where intermittently Google and sometimes Gmail won't load (or Google searches from awesome bar won't load). These are the only sites that seem to be affected. I don't get any error message, they just won't load. It happens several times per hour and lasts for several minutes and then sometimes they begin loading normally for a while without any intervention on my part. It sometimes affects Google only, sometimes Gmail only, and sometimes both at the same time. I have scoured the support forums and have tried everything I could find or think of, including: clear cache/site data, "forget about this site" in history, add exceptions to cookies and site data, change enhanced tracking settings, change "Do not track" settings, change connection settings to "No proxy", disable all extensions and themes (including LastPass, uBlock Origin, and Yet Another Smooth Scrolling WE), refresh Firefox, uninstall and reinstall, and create a new profile. The problem has persisted despite all of this! If I close Firefox and reopen it will correct the problem, and the sites will load normally for a while until it strikes again. Also, if I open a private window the sites will load, if I then close the private window and return to the regular browser tab, that will also allow the sites to load normally for a few minutes before the problem strikes again. Please help! I have happily used Firefox as my primary browser for 15+ years, but I am at my wits end and will have to find a new primary browser if I can't find a solution to this problem.
