Broken; cannot log in anymore

I used to use the LastPass addon a lot on my Android phone, but it became unusable after Firefox Quantum came out, and they still haven't fixed it. The length of time that this problem has gone unsolved is not acceptable.

I've used lastpass for years on desktop and android. I cannot get it to work at all Firefox 57 - attempting to login just produces a spinning cursor.

As a mobile Firefox add-on, Lastpass has NEVER, since october or november 2017 I think, managed to log in to the online vault with the passwords.
As a standalone app, I can login and view my credentials, search for website, username, copy password. But from within Firefox, when I click the Lastpass button in the login fields, it will loop forever trying to log in to Lastpass, without success.

Lastpass used to be a great tool, and I've subscribed to the service for years, but it no longer works in Firefox for Android. Can't get it to log into my Lastpass account. After entering my credentials, the cursor icon just spins indefinitely. In FF 57 for Windows, I also encounter problems, such as it often not prompting me to save new credentials or to fill in existing creds. The fact that the subscription fee doubled but the quality of the product deteriorated means I'll no longer be subscribing. Too bad because this used to be a frustration-free product.

Update: According to Lastpass support as of January 31, 2018, Lastpass will no longer be supporting their addon for the Android version of Firefox and suggests using another browser. Oh well.

Can't even log in

Can't log in so it is useless

Will not log in to my LastPass Families account on Firefox 57 for Android or Firefox 58 beta for Android.

It was great working across all devices. Still works on my desktop but no longer works on Firefox for Android v57. It just won't login. I have to use the app and copy and paste for months now. So annoying I won't be renewing my premium subscription as this product is so useless to me I might as well use a password protected spreadsheet containing a list of my usernames and passwords. The app is rubbish as well and rarely pops up to log into other apps anymore forcing copy and paste again.

Абсолютно криво работает с Firefox Quantum. Из-за этого часто даже приходится возвращаться на Chrome. Разработчики - вы можете, хотя бы, исправить баг, чтобы lastpass не требовал своего логина и пароля при каждом запуске Firefox? Это реально достаёт!..

he dont do autofill passwords and user names of local devices i must copy past it manuly

Does not work well with websites that use Web Components polyfill, for example https://polymer-project.org/ or https://cloudstitch.com/.

I reported this to LastPass more than 2 months ago and it is still not fixed.

After months still does not work on Android

Only works on about half the sites I visit.

Cannot sign into Lastpass at all.
