FIX FIREFOX EXTENSION AND LINUX SUPPORT!!

Seriously, you only need to support two browsers: Firefox and Chrome. IT IS NOT THAT HARD!

Linux COPY PASSWORD does not work. So you want me to open my passwords in plain sight so I can copy them, great security!

Does not install. Just says it is downloading over and over. Nothing else happens.

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

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....

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.
