I would rate 5 stars, but updates to the Firefox extension don't keep up with those to the Chrome extension. For example, Proton Pass introduced custom item types a while back, and within like a day, all their clients (mac, linux, chrome extension, etc) rolled out an updated version that supports them. Well, all except for the Firefox extension. Thus, custom item types can't even be seen - much less used - within Firefox. Otherwise this is a great extension with a pleasant UI.

simply perfect

It just works

Amazing App! And very stable on Firefox!

Better alternative to other password managers

Really smooth experience. Works out of the box with most online forms, however some sites or intranet pages won't get recognized. Still, it's easy to grab it from the pop up.

I am so beyond glad that this add-on exists! It's been working like a charm! 3 of my favorite things about this add-on
- the pop-up add-on window itself is the perfect size, which is especially commendable because there is nearly no functionality lost due to being crammed into a small box
- I love that I can add, update, and edit my Passes anywhere and anytime, without having to get into the Pass app
- it's easy to open up the Pass web app from the extension, though I haven't found myself needing to since downloading the add-on

Honestly, I already love the Proton system, and if this add-on didn't exist, I would never know I needed it. And there's the point of it all - you'll never know just how much you needed this little add-on until you use it!
Seriously, use it. It makes life so much easier!

Thanks Devs!
