I've been using Firefox Quantum for over a month now on Ubuntu 18.04. However, the extensions Grammarly and LastPass which I need the most do not work as expected. LastPass does not automatically sign in nor does the overlay interface work. I have to right-click on the extension button everytime and launch lastpass in a separate window to Sign in. Nor do I get a prompt to save the password when I create a user account on a website.

Next, Grammarly fails to work - and when it works, Firefox notifies that this extension is causing slowdowns, why?

Addons issue are not a FF issue for that you need to contact the Addon creator for support for their Addons issues.

I removed Grammarly from FF Addons but webpage loads very slowly or freezes with a message in a yellow bar on top - 'Temporarily disable Grammarly' or 'Stop it'. I have to Stop It very quickly every time before the yellow bar disappears.
