I'm having the same problem. Get a white triangle (envelope)? and am unable to log in until I remove LastPass and then undo it. What's going on?

Doesn't work correctly since after version 4.7.1

Frequently doesn't allow loading passwords, particularly on banking sites, where it's most important to use random passwords. Also with latest version of firefox, doesn't allow copying password from context menu, instead have to load the entire vault, VIEW the password, then copy it. Very time consuming.

Love this app. pro user for almost a year. not perfect but always being improved. Thanks LastPass!

Doesn't work correctly since after version 4.7.1. No overlay on the window when you click the icon, so it's unusable.

latest update renders the addon unusable on firefox :(

makes me regret auto updates

Someday I can not get rid of the mail address and password can not be saved. When will it cure?
I want you to make setting items so that notification of offline mode can also be hidden.

Doesnt save the Master Password. After restart of FF59 i have to login again. In newest Chrome/Opera it works.

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....

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...
