Sadly, this extension is increasingly buggy and has less functionality than the Chrome version. For example, you cannot right-click on a saved site and copy the password to the clipboard. And if you try to edit an entry by right-clicking, you get to an empty page. I hope they get their act together quickly or I'll have to find a different password manager.

Not working on 50.02. Immediately after putting in my user email, the addon vanishes. I've used the extension for years on Chrome.

love it

I have used lastpass ever sense it was put on the on sell.

Super convenient and easy to use. Will sync across multiple devices, can verify with finger print on mobile and see all passwords

Good application

Overall it is great, but with the Firefox extension (and unlike the extensions for other browsers), often an empty page is displayed when clicking "Edit", so one has to go via the Vault to edit saved passwords. Also it is a bit sad that one cannot copy the username/password directly from the extension, as can be done using the Chrome extension, but I guess this is because of the way that Firefox extensions work nowadays.

MAKES SENSE - SAVES TIME - VERY PROFESSIONALLY BUILT - smarter than we are!!!

Can't live without it! We use LastPass for personal & business and it is amazing! There are just too many password to remember nowadays and LastPass ensures that they are stored securely as well. We can't recommend it enough to our family, friends and clients!!

This extension was awesome, but it got so bad that I cannot stand it anymore, i'm looking for alternatives to lastpass

Windows don't close, some just open blank...

I had no problems with LastPass until I switched to Firefox. It stops working after 1 day! The only way to make it work again is to delete and add it again. Wasting my time. I considered going premium, but I think I am going to go the other way. Using LastPass has become too time consuming!

When it works is very nice. Problem is that many features do not work, or do not always work. And even if you are a premium client (I have the pay version) the technical support is very poor. A pity but I will do not pay next year. I am going to install a different password wallet

How to fix the broken version of the Plug-in

Lately, Lastpass has occasionally struggled with the add-on. The currently version (4.9.2) for Firefox is broken. You need to roll back to version 4.9.1.1 and things will work as expected. See this forum post: https://forums.lastpass.com/viewtopic.php?f=12&t=299455&start=30#p999975

For those complaining about the loss of functionality compared to the older versions (ability to easily copy passwords/usernames), you need to install the "Binary Component" which is NOT part of the new plugin but can easily be installed. See: https://lastpass.com/support.php?cmd=showfaq&id=5576

This extension is a mess and seem like it has been discontinued, as it lacks a lot of the core functionality it once had, such as the ability to copy/paste passwords wit one click.
Editing sites also doesn't work most of the time -- a blank tab opens.
The built-in vault is also borderline dysfunctional.

Sad!

Support for Firefox on Android was discontinued. But you have to go looking for that info.

The extensions still installs but it "loads forever" on the log-in screen.

If it's not supported, it shouldn't install in the first place. Lastpass is wasting people time.
