Every website I've tried doesn't ask to save a password when using Vivaldi on Manjaro Linux.
In fact, I had to do a password recovery on this site to post this because it didn't save my password when I signed up.
How do you save new logins? The browser extension never asks if I want to save new logins. I have the option checked in the app's settings.
I'm using the chrome extension on Vivaldi on Manjaro Linux.
