Stopped working in Firefox (56 and 59, desktop and laptop) and Waterfox (56) today. Clicking on toolbar icon shows a white triangle below toolbar icon and nothing pops up - no Vault, no nothing. Windows 8.1 64 bit. Working fine in Chrome, Vivaldi, and Opera latest versions. Removed, reinstalled older version, it worked briefly then back to white triangle below toolbar icon.

Update: Last Pass no longer saves new site logins. I get message that there was an error.

Otherwise, been using it for years and love it.

not usable any more
4.9.0 doesnt work
installed 4.7 again. OK

I can't open it in Firefox 52.7.3 (32 bity)
Instaled, but I Can't use it....

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

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.

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.

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

It sometimes works in Firefox. Most of the time it does not. The last update introduced catastrophic bugs to what was once a smooth experience. Your mileage may vary.

last update broken in firefox - cannot login anymore, when it happened to be logged in during the update, you cannot update anything anymore - says server taking too long to respond. It is as if it was working on a local cache of data that was no longer connected as it was old data. Works in chrome fine.

it is breaking the battlefield website of Firefox from now on

Doesn't remember trusted devices.

Cannot login on Android with two factor authentication, making this add-on completely useless, and Firefox as a whole useless for me on mobile. I'm forced to use Chrome as at least the LastPass app works with that.

I've used and enjoyed LastPass for the last several years. For the last three of these I've used the paid version.

But I've no plans to renew.

The reasons are simple. It's not real complicated. Nothing works as it should in the newer versions of CyberFox:

1. Despite options to save both fields of entered information, it does neither.

2. I have to completely re-logon (all fields wiped clean, without even the drop-down list of past screen-name email information) EVERY SINGLE TIME I launch my browser.

3. It no longer works, with any degree of consistency, to actually fill the empty boxes.

There are a few other minor annoyances not worth mentioning, but I gleam that this list albeit short is more than sufficient for a gist.

I'm disappointed.

When will LastPass fix the BUG in the Firefox Addon on Android that you can't Log in? I'm a Premium member and only get the answer in my Ticket that the developer works on it. Since 4 Month? Don't pay the developer for their work or fire them! That is a no go!

The functionality on Firefox is still severely restrictied due to not being able to copy usernames and passwords from the meny anymore (unlike in Chrome, where it works fine, so there it would get 4 or 5 stars from me).

password import from any Browser Build-in Manager is not possible

Il faut s’identifier à l'infini ! C'est insupportable !!!

Can't finish 2 factor login, just keeps asking for the one time code.

forse va su PC ma non è possibile che non funzioni su dispositivi mobili...
