Very good idea and extension!
Would love some more options with respect to the UX, I am pretty sure I will be able to put 5 stars in a near future.

LessPass works very well. Not requiring the syncing of an encrypted master password file is useful to be able to use this password manager on any device with ease.
Having the option to self-host your password options is a nice feature to have as well.
The main issue I have with this add-on is the need to constantly generate and then copy-and-paste the password into password fields. I feel like when focusing a password field in the browser there should be some shortcut to use LessPass to automatically generate and insert the password into the field. This is purely a user experience issue that I feel could add a great value but is by no means a reason to not use LessPass.

Très bonne idée de logiciel !

Great Add-on, Just what I was in search and wanted from a password manager!
