same here for me - setting up a new log in any random website, including this very enpass forum site as well, I don't receive any prompt from enpass. so I fill out each field and ask enpass desktop to generate a password for copy/paste into the website account creation. at least the desktop app lets me copy the password. if I use the enpass browser ext. to generate a password it won't place it onto the clip board and it will often only fill one field, not both. and then it will be complicated to hand type all the info to create a new entry in enpass desktop app. rather awkward and lengthy.
and, last but not least - it would be rather helpful to have an instruction page on this or enpass site, explaining how to do these simple things instead of letting a newbie struggle and possibly toss the whole enpass app, choosing lastpass instead.
I am using - firefox 50.0 on linux ubuntu 16
I have still yet to decide if I keep enpass and pay for the android extension.
