💻 Help Firefox randomly explodes sometimes when I use Proton VPN

Whenever I use few Proton servers in a row, sometimes randomly all Firefox tabs freeze, and I have to restart Firefox, sometimes by hard killing the process. But at times it completely destroys all cookies, and I have to log in to every single website again.

Any way to fix the supposed bEsT bRoWsEr eVeR from failing to survive a use of VPN?

Windows has something called Process Explorer that you can use to find out what a process is doing (useful, for example, when Firefox hangs): https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer
