I’m having trouble connecting to Google on LibreWolf when using the Mullvad VPN proxy, though it works fine on the Mullvad browser. This isn’t caused by extensions. Sometimes the issue flips: Reddit is inaccessible on the Mullvad browser but works on LibreWolf, yet LibreWolf never connects to Google while channeled through the VPN proxy. It should go without saying that YouTube doesn’t work either.
Am I misconfiguring something? Is using both a proxy and VPN in the browser excessive? The Mullvad browser is more reliable, but I prefer LibreWolf for its extensions. Constantly switching between them defeats my goal of browser isolation.
