It's a good plugin for password management, however it laks several functionalities compared its sibling Chrome plugin.

This add-on is really great. i love it

It does not work. Iclicl on the icon and no menu drops down. It does not log in. I need to go to the website to log in. This is only on firefox. Chrome works fine. NOT HAPPY!

what happened to webroot password manager i have webroot the only one i will use firefox is wrong from not using them

Does not work with Firefox on Ubuntu 18.04

Does not work within Firefox on Ubuntu. Using their website previously worked, but now Yubikey 2FA seems to be broken. And the lastpass website has a large number, 27 in fact, 3rd party ad-tracking cookies, as reported by the Duck-Duck-Go plugin. I am disappointed and might soon cancel my subscription.

Was recommended by my friend...

I had used this extension for quite a while on Chrome before switching to Firefox. Now, I can't even log in anymore, and it seems it's a problem quite a few people have too!

How about instead of requiring my auth code whenever I open my browser, only ask for it when I try to use LastPass

I don't know what all this complaining is about because LP works just fine (always does)
If you are having trouble with even the most basic functions, then there is something wrong with YOUR Firefox browser. Try a FF clean install, add LP as your first - and only - addon and see what happens. Win10, 64bit, most recent Firefox stable installed with UBOrigin active here

broken since a few weeks, can't login, going to password field closes the login window. Looks like it is only going for worse after logmein bought them. + the lack of response from the owner is a very bad omen (used to be in hours with the founders team).

Edit: @Firefox user 7bc37a, you are right, resetting Firefox or clean reinstall will resolve the LastPass auto log-off after exit issue.

5 Stars for being awesome for many years. Still the most trusted and secure password manager in the industry. One-star smear campaign from competitors won't change that fact.

I cannot even log in because when ever I click the textbox for password the pop-up closes.

lately something broke, cannot even login or enter my password. It seems there's a general trend people have issues lately....

I have used last pass premium for many years but recently so much basic functionality of a password manager has been removed that the browser add-on is more hassle than it is worth.
Last Pass seems more and more to emphasize 'Launching' sites through its interface. I never want to do this. I go to a site (through multiple paths) and then want to call on my password manager for my stored credentials. This basic workflow seems to be harder and harder with each release.
Commonly last pass will not correctly detect the site or fields in a login page due to some quirk of the websites design and that is fine. But last pass has made it increasingly difficult to get credentials out of it making it necessary to leave the web page, search for the site, edit it, show the password on screen and copy it to the clip board. This used to be some quick typing and a button press.
This add-on has gotten so bad that I am now investigating alternative solutions.
