My best solution to the login problem on stock Mullvad is to use KeepassXC with Autotype (if you’re on Linux with Wayland, use the experimental keepass snapshot). You can press the hotkey and autotype will pop up with a quick search for you to add the username and password. It can also save TOTP and passkeys. This of course doesn’t use any add-ons so its a decent solution to the problem.
Even with it streamlined like this, I still find it tedious lol. KeepassDX handles it so much better on android, wish linux could get functionality like that.
Yeah, I did that for a long time but I’m pretty done with it on most accounts. I only do it properly on the most important accounts.
