Has become worse and less reliable over the years.. The freshly installed version in FF57 allows to select the iconc (under preferences).. I have saved the settings. Nothing changed in FF. Closed the browser, and restarted. Result the old icons are back.
Does anyone actually check the basic working of a released program??
In addition the option 'save email' in the login screen does no longer work either. The email is blank every time I restart FF and go to the login screen (and yes the check mark 'save email' is set).

It finally works in the new Firefox, but right click to copy usernames and passwords doesn't exist like it did before, and does in chrome.

Probably just going to move to something else.

Seems to be missing some basic features of the previous FF and the current Chrome extension. The most useful of which is the right click > copy username/password features which I use constantly. Please put that back in so I don't have to switch to Chrome constantly.

Very good product, but very laggy on firefox

It seems to work fine on the new firefox, but for some reason, the button to 'copy password' is missing. This is frustrating

Terrible. Doesn't auto-fill in username and password on sites that used to work. The copy username/pass feature has also been replaced by the silly More > Edit functionality. Every time I need a password now, I have to Edit, show the password, copy it, go back to the tab, paste, and close the Edit tab. Will be switching to another password manager if this isn't fixed. This is on Firefox 57.

Tried moving to the new Firefox release, but the copy username/password feature is gone, making the extension basically useless. I can no longer easily access username and passwords for non browser applications, or when the extension does not correctly detect the fields.

Extension has gone from great to bad.

Missing site menu items; Copy User, Copy password.

Sometimes white arrow exists over Lastpass toolbar icon & it doesn't work.

After update, nothing worked the way it was supposed to.

I used to love this app. I still really like its convenience. but every update they put out breaks it in some way. They changed the way searching works apparently, and it broke the older version one time. Updating thankfully resolved that one. This latest update broke the functionality for copying the username/password from the icon if you search for a specific site. Now you have to open the 'edit' page to get that information.
I've tried uninstalling and installing the latest version, and no different. It appears to have broken the old version when they updated the app, and now the new version doesnt work either.

It's been great for years. But recently it works erratically and isn't worth the hassle. It won't automatically log in to several sites even after removing the site and then adding it once again to LP. It also, after removing it and then reinstalling it hoping to resolve the poor performance doesn't even offer an icon for the toolbar. I've had to resort to using FF's built in manager. It's really too bad as it use to be my most used, ad valued, add on

Version 4.2.1.21 is the worst version ever. It doesn’t work properly. What a moron published it. It doesn’t fill properly half of sites. Especially the ones with popping login prompt, they even don’t have special icon for fill. An the suggestion to store password for completely different page than it’s inputted. Disaster. First Xmarks, now Last Pass. Both correlated products are useless now. And no fix on the way. Sorry but I’am looking for alternatives, after all the years.

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.

Autofill not working, and can't copy usernames or passwords.

Settings are no longer preserved, I have to re-enter not just my password but my login username as well, whenever I start Firefox!. lso, settings like language are no longer retained.

If it is not fixed SOON, I will definitely switch to other options!
