In version 4.2.1.21a, they removed the ability to copy a site's username and password. This was a very handy feature when copy/pasting to an application or to a website where LP didn't automatically detect the u/n and p/w fields.

LastPass is now useless without the ability to copy the username and password.

The best part is that it saves you from browser lock-in.

Yes, I do.

Used to work great - now worthless on Android Firefox. I have been a premium user for a long time and now am going to find something that works. Lastpass support site worthless.

I love LastPass, would be lost without it.
But that's the problem, this is the third time in the last 2 weeks that it has just disappeared from my Firefox icons toolbar. Once again I have had to reinstall it, which is very frustrating.

Also my password is quite long and complicated, and there is no way to make it visible when I enter it, so I often have to type it several times. LastPass doesn't even warm me when capslock is on.

Otherwise a great program, have used it for years.

Fingerauthentication does not work anymore

Copy password function is missing in the new webextension version. Please add it!

Extension stopped working in Firefox/Waterfox. Used to work flawlessly and seamlessly across different devices and operating systems. Still does on everything except Windows8.1, latest version of Firefox/Waterfox..

I've been using the WebExtension version since beta. Though if was very buggy at first it's constantly improving and now I consider it to be very useful. There are several minor issue that still need to be resolved but for the final version of FF57 it seems to be working just fine. I'm hoping Lastpass will continue to improve the extension and enable attached ASAP.

Was superb, now is utter garbage. This morning, for the second time in a couple of weeks, the addon acts as if I have no data stored whatsoever. When I log into the LastPass website my account is fine. It's just the addon that keeps completely failing. I suspect it is related to the changes required to make it work with Firefox 57, which is proving to be a disaster.
