Constantly logs me out, regardless of settings. Doesn't work on many sites, even sites where it used to work. Vault screen does not occupy the full browser screen. In general difficult to use and getting worse.

I wish LastPass had templates and direct functionality with iOS apps, but that might be impossible given how tightliy controlled Apple is with system api

Раньше работал,сейчас значок оранжевый и не открывает пароли...!!!херня!

Every time Mozilla update their browser this year I lose LastPass and therefore all my passwords and then have nothing but trouble re-instating it. Now looking elsewhere

I would go NuTz if I didn't have Lastpass. My professional and personal accounts exceed 250 in number!
Imagine memorizing 250+ usernames and passwords!? This software is a Godsend. I was going to dock Lastpass 1/2 of a star, but I have a feeling that the few credential spaces it fails to fill in are because they are being actively blocked with javascript by organizations like Wells Fargo and American Express. I went with the premium service. For a service this good, they should be paid something for it.
Update:
I've had to contact support a few times for issues with multifactorial authentication and adjustments for my VPN. They always respond quickly and are very helpful.

We love you

It simply is not working on my machine.

I like it. I can't do without it!
Thank you to the development company!

Not always reliable, ambiguous instructions. For example: "matching logins". Does that mean to do something?

I really liked LastPass. Started using it almost 2 months ago. In the last few days the Firefox extension auto-updated to some non-functional version and instead of menu dropping down from the icon in the toolbar, it only shows a white triangle in the bar. I use Waterfox now on one PC and have the same happening. I uninstall the extension, go back to LastPass website and install again and it works fine until next auto-update happens.
Fix this! If it is incompatible with some Firefox version, don't push it to install!

On Firefox 59.0.2, right-click to copy password doesn't work. It works when I use the lastpass.com web site, so what's the point of even having this extension if I don't use it to auto-login to web sites?

regarding FF ESR v52.7.3 , LastPass has been broken due to the update. Following @Iconoclast's advice resolved the issue for me on OSX with only restarting the browser. ie, remove the lastpass extension, restart browser, install lastpass extension from lastpass.com (not adddons.mozilla.org), disable updates in `about:addons`.

it doesn't work with two factor authentification. i cannot login.

The update on 03/30/18 broke the Lastpass for Firefox extension if you are using Firefox ESR (Extended Support Release) which is a slightly older version of Firefox. The new extension update does work on the newest version of Firefox. TO FIX THIS PROBLEM: Go into your Firefox addons and remove the Firefox extension. Close Firefox and log out of Windows or restart the computer. Log back in, then start Firefox. Go to the LastPass web site and install the LastPass extension from there, It will know to install the older version of the extension that is still compatible with Firefox ESR and older versions. Then you can login and everything will be working. Go into your Firefox addons again, click on More then scroll to the bottom and turn the automatic update to OFF. You can check back in the Firefox forums to see when the problem gets fixed so you can know when to update the addon again. I gave the extension 4 stars because Firefox and LastPass have trouble getting along. Of course Firefox has trouble getting alone with pretty much all addons these days. When the LastPass extension is working it's awesome and I rely heavily on it and I'm a Premium Subscriber, but I am really sick of the problems Firefox has with addons as well as them taking away the ability to customize the UI. Anyway, I hope this helps you all! Peace.
