Since changing owners this plugin is getting 'buggy'. They're changing the graphic UX but the functionality of the plugin in Firefox is not consistent anymore and small annoying bugs are slipping into the extension. Anything from small things like the cursor not being on focus in the password field when you have to fill in your password to bigger things like empty pages with just the Laspass logo appearing when you're supposed to log in. Also: sometimes the site is recognized because it's shown under the last-pass icon, but it refuses to automatically fill in the password.

It's a free password manager, so that's great. But I can't help but feel there are slowly creeping more and more bugs into the Firefox extension. Spinning wheel bug is a known one. But also it can get stuck in a clipboard permissions request error which then doesn't redirect to the actual permissions request. Also, there are lots of tiny annoying visual things that haven't been fixed for years. So for a free password manager, I guess not bad at all, but for a paid one I would consider other options.

LastPass stopped loading automatically on Firefox. I need to sign into it every time I open Firefox. Not true on other browsers.

Superbe extension, indispensable, sauf qu'il ne fonctionne que la moitié du temps !

Not able to login into the extension

No funciona bien con aplicaciones que tienen pop-up login.
No siempre está activa la aplicación.
En general es una buena aplicación pero cuesta activarla.

The app is buggy. After Sept. 16 2020 update I cannot log into the app on my PC, have to use a one time password half the time

Take a good look at the privacy policy before you install this! Please note that you are also giving privacy permissions to this app related to Google and related to LogMeIn.com
All of this looks legitimate. However, as with Google and Facebook, LogMeIn seeks to combine information collected through the app with information about me which that company will collect FROM OTHER SOURCES. Even if it's mostly for app functionality and marketing purposes. I don't need any more advertising or spam than I already get!

This add-on doesn't stay with Firefox. Every time I open Firefox I have to re-download LastPass.

Works as advertised except one: I have 2FA activated and I am infuriated by constant re-authorization prompts, despite ticking to remember the browser. I am nagged at least once a day on all my browsers.
