Firefox Issue when using 'New Tab Override' Add-on
I'm having problems logging into any/all Wordpress dashboards following the latest Firefox (V127) update. The 'verifying' screen continues to cycle but doesn't produce the login screen. I can get them to work in Troubleshooting Mode. This also works when the 'New Tab Override' Add-on is disabled too. I've tried ALL of the recommended custom tab plugins with the same results, so it suggests a common incompatibility.
Have cleared cookies and browser cache. WP login works on all other browsers.
Would be grateful for any help and/or suggestions.

This sounds more like a problem with a content blocking extension.
If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, 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

You can try these steps in case of issues with webpages:
You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.
- hold down the Shift key and left-click the Reload button
- press "Ctrl+F5" or press "Ctrl+Shift+R" (Windows,Linux)
- press "Command+Shift+R" (Mac)
Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings), click the padlock icon (Clear cookies and site data) for the domain in the selected tab.
"Remove the Cookies" for websites that cause problems:
- Settings -> Privacy & Security
Cookies and Site Data: "Manage Data"
"Clear the Cache":
- Settings -> Privacy & Security
Cookies and Site Data -> Clear Data -> [X] Cached Web Content -> Clear

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.
- switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

You can check for issues with Enhanced Tracking Protection. 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.
- click the shield icon for more detail and possibly disable the protection
You can check the Web Console for relevant-looking messages like about blocked content.
