Serious Problem: How reliable are VPN extensions like MullVad VPN for Firefox?

I appreciate your replies!

I’m REALLY struggling with this because I need to exit all of my Apps on my Win10 Pro PC and only then can I open and connect my VPN but this is a tedious process..:

This is why me being able to use a VPN without needing to exit any other Apps on my Win10 Pro PC would be amazing.

Do many users only have their VPN turned on and working from within their browser whether that’s Brave, Firefox or Mullvad? I’ve never tried this before…
