This is the error I constantly receive:
The owner of addons.cdn.mozilla.net has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.

Up until quantum , this plugin worked fine. Totally unusable now ( logouts/missing features/slow). Maybe Firefox devs should fix this instead of waiting for Lastpass, because no one will use your browser until this is fixed.

Too many glitches. More and more websites where LastPass doesn't work properly, also very slow to react. Probably a FireFox problem, because it's getting more and more glitchy too. LastPass works much better on Chrome and IE.

Wreszcie bezpiecznie i spokojnie, że hasła nie zapomnę!

Well the import doesn't work so it's completely useless for migrating everything I have from a local KeePass database. Definitely won't be paying for premium.

I thnk it's one of the best password managers but lately, in the last few days, I get randomly logged out from the extension and have to log in again, which kind of defeats the purpose of saving time... =/

I'm a long term user and paying customer. One could say I really like Lastpass. It's a very useful password manager and has been part of my digital life now for quite some time.
But...
PLEASE FINALLY FIX THE FIREFOX ADDON FOR ANDROID!

I've been using LastPass for 7+ years and have been a paying customer for 4+ years. I love it, have no complaints, and recommend it to everyone!

Rubbish. Even after it being installed in Firefox it is saying it is not installed when trying to recover account, stupid waste of time and dangerous.

Everything is in one place and I don't have to remember all those password s

It's my daily use extension but it make the browser slow.

FF keeps logging me out of LASTPASS. LP works great in CHROME! I suspect its FIREFOX which has become so crappy in performance, with issues, bugs, crashes... I dont want to leave FF but i think i might...

This is actually a great extention for managing all my passwords and everything that I need like notes and stuff on one place...

I've been a paying customer for a while now, and have convinced multiple people to start using this service. It has been high quality, robust, and convenient.

In the past few months I've been noticing little things here and there; gaps, missing features, glitchy behavior, etc. I figured that some of this was due to the transition to the new Firefox plugin system, and gave them the benefit of the doubt. It worked, and I do strange things to/with my browser that could affect the behavior.

However, I can no longer click on, or tab to, the password field in the Firefox browser extension. I'm on a fresh installation of the latest Ubuntu Linux (18.04) and latest Firefox (60.0.1). This bug is also present in other Firefox installations, rendering LastPass unusable.

@LastPass: Please stabilize the Firefox plugin, so that I don't have to spend time searching for an alternate vendor.

I'm done...headed back to Google Chrome b/c the Lastpass Firefox plugin is so ridiculously broken. Sadly I guess that gives Lastpass no real incentive to fix it if we all flee back to a platform where it does work.

This it the greatest password manager and it is cloud based and encrypted so it's available everywhere. The only problem is FIREFOX!! Firefox keeps hiding the icon at the top of the screen and there is no way to get it back!! I have to take the time to reinstall it. FireFox keeps randomly hiding all my icons at the top!! Please stop doing that.

Todo aún en free es genial

Constantly being broken. Do you not test things?
Google Authenticator doesn't even work in v4.10.1.0, code entry page loads blank with javascript errors: TypeError: getBG(...) is null 1 toolstrip.js:1:10124

And you still haven't fixed not being able to select other accounts from the login dialog. The dropdown list can't be opened by clicking if there's an email filled. That is not how dropdown lists work.
