Even before the leap to Quantum by Firefox, I was already having issues with the LastPass Add-On. It did not retain the preferences I set and it was acting "clunky" unlike before when it was doing just great. After Quantum, I sent a support ticket and I got a reply on 12/29/17. I guess I did not read the reply carefully. I just downloaded the latest LastPass Firefox Install which did not solve the issues. Well, today I read the support ticket again which specifically said to download the Universal LastPass Installer, uninstall my current version, reboot and install the Universal version. I did that then did another reboot/restart of my PC and after a few tries (3 or 4) on Firefox (logging in and out of the Add-on and/or restarting Firefox), I got it to work. My preferences are retained, my vault is displayed correctly, the remember my PC/device feature works, etc.

I just rated it 4 stars because there's always room for improvement. And I'd say that the engineers should be on top of this as this app is vital to users' security. You need to be a step ahead.

Lastpass and firefox... Are the best thing since sliced bread

It just works.

相比支持56之前旧版，缺少了一些功能，比如复制密码，现在只能跳转到编辑界面再复制密码了。相比chrome的版本差太多功能了。

Firefox側の制限で、BASIC認証画面のパスワードが自動入力できなくなってしまったのが辛いですね。
それ以外は新しいブラウザにも対応していて、使いやすいです。

Gets confused sometimes

Generally a good app, but needs updates to work best with Firefox Quantum. I miss the ability to manually copy-paste usernames and passwords on sites where the app can't recognize the login fields correctly.

It seems alright. The biggest issue I have with it is the option to automatically log out after inactivity isn't very useful, because it's based on general *browser* activity, NOT *LastPass* activity; so it stays logged in as long as you're using your browser. What I would really like to see is for it to log out after every login, so you have to type the master password for every use. While you can configure individual passwords to require the master password each time, you'll still have to log in first; so if you haven't used LastPass yet during a browser session, you'll need to enter your master password twice--once to log into your LastPass account, and again to fill the password in question. Also, the "open extension pages in dialogs" option doesn't work well.
