I've used LastPass as my primary password manager for years.
I use it almost in all my devices and browsers without major problems.
However, this app on Firefox is significantly worse than all the other LP apps.

It is so bad it makes me wanna use a static HTML file with all my passwords that goes away after I close the browser bad.

I love LP but their Firefox app is trash, specially if you use FF in Ubuntu.
Please make it better!
