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.

A good password manager but the ADD-ON is constantly having issues with Firefox.

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.

Sencillo de usar y muy conveniente

Nutze LastPass seit vielen Jahren und bin vollkommen zufrieden.

Awesome

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.
