EXPORT PASSWORDS IS BROKEN in the Firefox add-on (but works at lastpass.com) and same is true for vault view. I've used this for years, but the latest update continues a downward trend by making the vault almost unusable on Firefox. There is a notice to enable permissions _behind_ (lower z-order) the display of items, asking me to give it permission to access and collect web addresses, which I can't click on. Furthermore, LastPass already _has_ that permission according to the Add-Ons page in Firefox. Past downgrades have included increasingly poor performance, which for some reason is particulalry a problem in online learning environments that use or support Learning Tool Integration (LTI), such as Canvas, Sapling Learning, and the Zoom LTI plugin for Canvas. LastPass will do things like slow down the Sapling gradebook display, such that Firefox repeatedly pops up "An add-on is slowing down your browser --- Last Pass" and ask me if I want to disable it. It also interferes with watching any Zoom cloud recordings that have password protection, on my university zoom domain, by overwriting the video-specific password with a password for a zoom account on a completely different domain. It's just not what it used to be. At least please fix the broken vault display.

Ive been using LastPass for years, but the fact that I have to constantly reinstall the add-on just to use Firefox is frustrating. LastPass keeps breaking Firefox, not allowing any pages to load. The only solution is to uninstall the add-on, and reinstall it. I have always recommended LastPass to others in the past, but it looks like I will have to find an alternative solution for myself and my future recommendations.

Broken in latest version of firefox on both windows and linux

Currently broken in FF , PLEASE FIX ASAP!!! I spent the entire morning freaking out because I didn't have my passwords saved in another location. In FF a work around is to go to your add ons manager and disable/enable the application you'll then get the older looking log in prompt which works. FIX IT NOW please!

This is the THE MOST FRUSTRATING THING I have ever encountered. I can find NO WAY to get to a human being to help me. I am stuck on page in FireFox about ADD Ons, but can't seem to get anywhere.

UPDATE Sep 22, 2020.
Still not working. Updated Firefox, uninstalled & reinstalled Lastpass. No Luck.
I used to like and use this Firefox plug in but since past week it is not working on my Windows 10 desktop. I can't login at all. All I get is a message "an unknown error occurred"
Looking at alternatives to Lastpass.

I installed, I guess, and the next screen says almost done, click LastPass browser button above to login. But there is no browser to click.

Had trouble with the Auto Fill feature sometimes not working, overall a good extension now they decide to limit features for long time free users such as myself out of no where. No thanks, Bye. Bitwarden here I come!

Nightmare experience. Will use a better alternate if available

crap! it is not working while logged in... not filling, not recognizing, not opening the dropdown window... not in firefox and not even in chrome... i think seriously about migrating to other plugin

not sure yet hope i can login STILL CAN"T LOG IN

I generally like LastPass as a service, and have good experiences with their Chrome extension and command line client, but this Firefox addon is clearly not a first-class citizen for them. It is poorly and inconsistently maintained, and regularly breaks Firefox's fundamental purpose...to be a web browser...on multiple platforms; I can attest to Pop!_OS and Windows 10 personally, but while troubleshooting this problem, have run across reports from a variety of other OS flavors. When the LastPass extension is enabled, only Mozilla sites connect and render. Any other web page or remote service the browser attempts to connect with, including lastpass.com itself, just sits there animating the bouncing ball in the browser tab, but otherwise does nothing. The operation also never times out or throws an error. Additionally, it renders other extensions inaccessible/non-functional via their quick access icons. As another reviewer pointed out, the only workaround is to fully uninstall and reinstall the extension (and restart Firefox afterwards) anytime Firefox updates or has a config change. This is not acceptable for a paid service that promotes its browser extension as the primary interface.

I love the password vault, it holds my passwords and I can get to them. That part is great. The problem I have is the firefox addon. When I log into lastpass, the log in works, but afterwards, I cannot access any websites, so I have to go to my addon manager, remove last pass, and reinstall it. I have to do this several times a day. It was working perfecty, but now, not so much. I have a subscription that I have had for several years, that I am thinking of canceling if they don't fix this issue.

Не понятно как работает импорт/экспорт, во время экспорта вообще ничего не происходит кроме запроса пароля. Не хватает русского языка.

It is not clear how import/export works. during export, nothing happens at all except the password request. I don't have enough Russian.

No longer supported. Don't bother installing.

The developers of this are thick morons. Doesn't work on Firefox for Android and their dedicated Android app is garbage.

Werkt bij mij niet in de Firefox browser op Android telefoon. Je krijgt een inlogscherm te zien, en je kan proberen in te loggen tot je een ons weegt, maar er gebeurt niks.

Delete..

Please update in FireFox Android, i't not working

Broke sites from working. Like 9gag stopped loading images when lastpass is enabled. Did lastpass got merged to another company because it's begging to get broken slow and it just suck.

Does not work

Doesn't work. Doesn't let me log in at all. Don't waste your time. I'm a Long time Lastpass user. Just bring back the long press in the password field and leave it at that. Stop messing around with trying to detect the password field.
