I have previously tested 1Password and LastPass, and two nice features are:
an icon inline on a form that recognizes a password field to help you generate a password for the creation of some account
once you create a new account on a form, even if you did not open the extension, a request to save the new credentials along with the URL
I am interested if someone in the bitwarden community is already on this as I only see people on the user-to-user support declaring that one must actually open the extension. I happy to develop it if no one has it in the works. I have yet to build on the project so if anyone has already begun dev, let me know and I am happy to help.
