I'm not sure what went wrong in p4cm4n's review, but the option to save logins to the db appears when you right click the extension's button. The generation is there too. Overall its slightly less seamless than PassIFox was, but I suspect that is due to the nature of WebExtensions.

Very light, does not require restart, and identifies most sites.
Had some issues with the UI at first - the action buttons were not displaying at all at it was unclear how to use. The documentation contains the list of hotkeys, though.
It works fairly well, either standalone or supplementing KeeFox in finding sites that the other plugin misses.

It seems to be functioning very well so far.
