I us this everyday on all my device

Not usable in Android. Getting an infinite spinning wheel when try to log in.

It sometimes doesn't want to insert my login details, but v4.9 works only with Firefox Quantum for me.
I normally use Cyberfox, based on Firefox 52 ESR, and had to revert to version LastPass 4.7.1 since 4.9 does not work in Cyberfox.

变差了，原来的功能都给阉割了

I will change this rating to 5 if you bring back:
- the "Copy password" menu item
- and when I click on the LastPass icon put default focus on the "Search LastPass Vault" textbox, so I can start typing at once without clicking on it

These features used to work before the Firefox Quantum release...

Didn't work. Extension menu was shrunken. probably a dpi problem.

Abject. Keeps breaking, fails to fill in passwords on some sites, forces me to copy/paste from the clipboard. No software has made me curse louder or longer, and I pay money for this. I've been a subscriber since 2014. The quality has got steadily worse, I'm uninstalling it and cancelling my subscription even though it has almost a full year to run.

Generally, I like this tool. It's not much hassle and most of the time, it stays out of my way.

why does the button "remember password" have no effect?

After all these years LastPass for Firefox Mobile is still completely unreliable and utterly crap. Sometimes it works, probably by accident or the position of the moon (who knows, certainly not the LastPass devs), most the time it doesn't. Not worth paying for anymore, unless you like getting frustrated.

Habe es soeben installiert.

呵呵呵，好用啊。

Tried this, but it slowed down Firefox substantially. Uninstalled.

working on all platforms

Works very well across all platforms, have had zero problems in using this program/app/addon.

I recently switched from Chrome to Firefox. I was using the LastPass extension in Chrome before, and noticed some differences with the Firefox add-on, that reduce the user experience for me:
- when clicking the LastPass button in the menu bar, you cannot type right away (e.g. entering your lastpass password when logged out, or entering a search in your vault when logged in). You need to click the password or search box, before you can type.
- when searching for a password, there is no option 'Copy password' like in the Chrome extension.
