   A customizable-domain proxy client is great, but some Windows apps, like   
   Thunderbird/Betterbird, won't use the intelligent PAC file to determine   
   which domains should bypass the proxy and which should be tunneled.   
      
   I'm not sure which mail domains are finicky (e.g., protonmail?) but in my   
   experience, Google's servers hate it when I use VPN and/or SOCKS proxy.   
      
   So the simplest option is to turn off the TB/BB proxy setting altogether.   
      
   I'm in Betterbird 102.10.1-bb34 (64-bit) where the settings to make   
   Betterbird connect directly to Gmail (without using a proxy) are...   
    1. Start Betterbird 102.10.1-bb34   
    2. Go to "Tools > Settings > General"   
    3. Scroll down to "Network & Disk Space"   
    4. Click the "Connection" [Settings...] button.   
    5. In the Connection Settings dialog is a section titled   
       "Configure Proxies to Access the Internet"   
    6. The default is "Use system proxy settings"   
    7. Change that to "No proxy" if you're using GMail, which is finicky.   
    8. Click "OK" to save and exit.   
      
   This should be exactly the same for Thunderbird since BetterBird   
   improvements don't extend to the proxy mechanism of Thunderbird.   
      
   Turning off the proxy mechanism ensures Betterbird bypasses any SOCKS proxy   
   or system proxy settings and connects directly to Gmail servers using the   
   normal internet connection.   
      
   If you know of a way to get TB to respect Windows PAC files, let me know!
