Currently nearly unusable on Linux.
Will not:
form fill
allow copy of username
allow copy of password

Is also slow to recognize text entry boxes for username/password, which leads me to have to right-click and follow the menu items to fill in passwords.

I've used LastPass as my primary password manager for years.
I use it almost in all my devices and browsers without major problems.
However, this app on Firefox is significantly worse than all the other LP apps.

It is so bad it makes me wanna use a static HTML file with all my passwords that goes away after I close the browser bad.

I love LP but their Firefox app is trash, specially if you use FF in Ubuntu.
Please make it better!

Блестящее расширение, оно не только надежно хранит пароли, но и невероятно удобное в использовании. После авторизации в LastPass логины и пароли автоматически вводятся на посещаемых вами сайтах, вам даже не надо помнить регистрировались ли вы до этого на сайте или нет, LastPass все сам находит в своем хранилище. Как только вы зашли на знакомый вам сайт на значке расширения появляется число, соответствующее числу сохраненных комбинаций логин/пароль для данного сайта, таким образом при наличии нескольких аккаунтов на сайте, можно выбирать под каким из них авторизовываться. Для обеспечения более высокого уровня безопасности LastPass можно по желанию настроить таким образом, чтобы автоматически производился выход из него после простоя через любое настраиваемое пользователем количество времени.

Randomly logout on its own during a browsing session. Have to open up the program in a full tab to login as others have stated. Sadly this used to be a really good add-on.

LastPass and Xmarks were the top of the heap for years, I could not have sung their praises more loudly. And used them for many years and would even have gone premium many times over if they accepted PayPal as I let them know a few times. But they never did support PayPal for subscriptions and so I never went premium.

Then the crisis hit. They retired Xmarks (boo, shame, hiss) and they retired the Android support (booo, hiss) and our relationship is over. Goodbye Lastpass, it was nice knowing you we had a lovely relationship and the divorce is amicable if disappointing, wishing you all the best, but I'm keeping kids thanks and moving on.

So my password children are all with Bitwarden now which is FOSS (free and always free, open source and on github) and KeePassXC for the banking ones (local secure storage and also FOSS and on github) and all my bookmarks (which were with Xmarks) are now with floccus/NextCloud and I'm now happily moving on with my kids and wish LastPass all the best in her coming relationships, but deny her any more influence over the children.

Her business model is simple a sad failure it seems. She was never willing to take my money when I wanted to offer it, and she withdrew all her love step by step ...

Adios.

UPDATE: Finally, after 6 months of having to log in to LastPass every time I opened my browser, and getting a funky blank mini filed when I clicked on the LastPass toolbar icon, it began to work again with the last FireFox update. The tiny empty window still shows for a second before it is covered by the larger LastPass menu. Six months is WAY too long for an update to a problem in something as essential as a password manager, so still subtracting a star for that.

ORIGINAL REVIEW: This used to be a great add-on for a great program, but it has been weeks since the last update screwed up everything for a whole lot of customers, and LastPass obviously couldn't care less. WTH LastPass??!! Do you have some kind of issue with Mozilla? Does that make it OK to treat your FireFox customers like dirt?? Needless to say, I stopped recommending LastPass to my clients. A password manager MUST be absolutely reliable, not to mention above any kind of b2b gameplaying or whatever is going on.

se non posso copiare le passwords diventa inutile

No right-click/general dialogue to directly copy a username or password on a website almost breaks the extension. Forms aren't always perfect, and I save more than just web passwords here. It's basic, it's necessary.

I LOVE this add-on/APP! Always room 4 improvement, but as close to perfect as we humans can get on this Planet!

Since a few weeks Firefox crashes when I sign in on my lastpass add-on. Sometimes it helps when I sign in via the website instead of the add-on, sometimes I need to remove and re-install the whole add-on. It's a pain.

Depuis la dernière MAJ de Firefos, le module ne fonctionne plus du tout... dommage car il était parfait auparavant.

I love lastpass and use it daily, but lately the addon has not been working with firefox. It logs me out and is not usable after hitting login. Please fix!

This addon causes my firefox to hang while loading web pages

This addon has nice features when its working. Unfortunately, it seems to crash every few days or so. After crashing, clicking the icon only produces a tiny, empty window. Usually the problem resolves itself after a complete reboot. I'm using Firefox Quantum 60.0.2 (64-bit).

from first to worst for Firefox on windows 10. Linux Firefox works good. NOW it does not remember email, drop down stays tiny useless. The app does not open when you want it to. No longer support for Firefox from my perspective. Moving on to other solutions at this point.
