I hope the Proton team is putting a lot of effort into this extension because currently, it's not working well at all. I'd say that it only offers to autofill my info on about 50% of the sites I've tried to use it on. When I enter new login info for a website, it pretty much NEVER offers to remember it. I would submit bug reports, but I don't want to take the time because it doesn't work more often than it does. I really wish there was a standalone app for Windows instead of only the browser extension because I'd like to be able to use it for passwords that are outside of the browser as well. I also worry that there could be security vulnerabilities that are due to the browser and extension ecosystem. I'm a paid subscriber and rather disappointed, at the moment.
