I've tested this in Chromium and in Firefox. In Firefox, it is currently Experimental but seems to work okay.
It won't work with Firefox ESR, only Firefox release channel. It would be much easier for me and probably many others who use Firefox ESR in Linux; no need to install two different versions of Firefox.

Maybe I need to change my workflow, but one feature of BitWarden I like is the ability to pop-out the window of the extension. This comes in handy when you need to toggle between the password manager and the page open in the browser or in a browser on a different monitor. With Proton Pass, better not get half-way through creating an alias or login and click outside the extension... or you have to start over.

Same than Lautaro

Very soon Proton Pass will place LastPass in my rearview mirror Thank you proton you all Rock Steady. So far I have not noticed any bugs, another sound addition to the Proton Portfolio. Wow I sound like a fanboi!

Why do I have to keep filling in my gmail account and password?

Don't ask you know

Thank you so much. I've been waiting for him for so long. it's just super. something incredible.

My company has no way to connect to any email provider, nor does it accept traffic from anyone that is presented as a VPN. The Protonmail homepage is also unreachable, of course. I know I can't use Proton e-mail at work. However, can anything be done to make the Proton Pass delivered differently? So that it is not recognized as mail or VPN... Just like Last Pass does.

some websites won't show the autofill suggestion! Hoping for better Performance updates soon!

So good so far and so happy you have added this. Now I can get rid of my old Norton Password Manager - albeit no import option for this manager. So only 4 stars since cannot import from that.
