I love everything about Proton Pass. It is lightweight, offers all the features I want, and it is makes it easy to store not just passwords, but other info too like serial numbers, SSH keys, identity information, etc. Not to mention their security is topnotch, and I the resource usage appears to be minimal in Firefox.

+1 star more!

Best manager of them all

Idk how this compares to other password managers, but this is way better than my previous one (Firefox's built-in manager)

Proton Pass works really well on most sites, though occasionally an email fills in where a username should or it doesn't show up on a specific site but that seems to be really rare and has only happened on one out of 300+ I've saved
