some sites only work properly in private window, still a/o 81.0
Certain sites will not work correctly in FF regular window, only in private window. Don't know if it is FF or the sites problem. FF many versions, currently running on Debian10. 2 examples.
1: trying to login to StateFarm.com always gives this error in regular window; no error in private window:
< pre><!doctype html>
<!--[if lt IE 9]> <html class="lt-ie9" lang="en"> <![endif]-->
<!--[if gt IE 8]><!--> <html lang="en"> <!--<![endif]-->

Error code: Technical Error 404
2: I login to CVS.com in regular window, select a prescription to refill, click link to process order and get a blank page. Private window works correctly.

Some differences between regular tabs and private window tabs:
(1) Private windows do not use cached files from regular tabs -- to equalize that, you can try clearing cached files: How to clear the Firefox cache (make sure not to clear all cookies while you're clearing the cache)
(3) Extensions do not run in private windows by default, they have to be individually enabled -- so possibly one of the extensions that runs in regular windows and not in private windows is causing the problem?
(4) Private windows may have a higher level of content blocking through the Enhanced Tracking Protection feature -- but for those types of sites, I don't think this would be helping
I do notice content blocking extensions like Privacy Badger and uBlock Origin in your System Details list, so it is possible that you haven't enabled these in PB mode.
If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.
- make sure your extensions and filters are updated to the latest version
Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content. You can click shield icon for more detail and possibly disable the protection. You can check the Web Console for messages about blocked content.
