Very disappointing that it doesn't have feature parity with the Chrome extension.
"Copy Username" and "Copy Password" are the features I miss the most.

As a former long time Last Pass Premium user, I had to give it up and move to Roboform. Several versions ago, LP stopped automatically filling forms and took several clicks to do what was once automatic. After contacting their tech support, who were very RUDE, I decided to move on to Roboform. It works great IF you have the Windows Client installed

This addon doesn't import Firefox saved passwords

Not working with Firefox 58

I would love to be able to "Copy Password" from the Add-On menu. Right now, I have to click "Edit" and then manually select and copy the password from the site detail in my vault. This functionality exists in Chrome and it would be great to see it in Firefox too.

My experience echoes many recent entries. I have been unable to log into the extension and have to copy and paste from the app. As a premium user I am now examining alternatives. No fault of FF but very disappointed by Lastpass.

Never logs in, keeps getting stuck on the login.

Bardzo dobry menadżer haseł

Its awesome & easy to use.

LastPass Dropped the ball with the extension as of late. I don't enjoy using it anymore and i will cancel my premium account soon.
