Overall pretty good! Firefox extension doesn't have the features that the Chrome add-on does. It won't let me choose to fill either the password or username. I have to open the site's info in another tab and copy/paste. Just wastes time.

In chrome, I have many more options when I use the extension, such as being able to manually select what I want to copy (user name or password) I don't see why this isnt a feature on firefox. This is useful on website that either change up how they want data entered or LP can't read the code and input data itself.

Ok

Unlike previous versions, you can't right click a site and select "Copy Password". Instead, I have to edit the field to do this.

Working better than it did, but what happened to copy username/password? Real easy two-click way when autofill didn't work. Now I have to go into the vault, find the login, edit, click the eyeball icon, and copy/paste.

Until a few month ago, I would have given LastPass 5 stars without the slightest hesitation but, in its current state, the practicality of LastPass is thrown out the window. It still stores my passwords just fine, but in actual use it's suddenly very cumbersome.
Most serious, the copy password / username option is gone. Instead one has to open edit password, make password visible, copy and finally close the window manually. It's might not seem like such a big deal, but the 10th time in one browsing session, it starts getting annoying.
Other new headaches include the lost auto-focus when logging in or searching sites, and the password generator working less well.
The years of positive experience in the past make me stick to LastPass for now. I'm not keen on the process of researching and migrating to another password manager, but I admit that I have started to look for alternatives, in case these things are not solved reasonably soon.
I would not recommend to start using LastPass at the moment.

Why i can't copy like before? I have to 'edit' before I copy my password!

Two-factor authentication is bugged. If I fail to pass the second step within like 2 minutes after entering my password, the extension won't accept the code, and won't react to subsequent attempts to enter the password (I open the login window, enter the password, and then the window just closes and nothing happens). I need to reopen Firefox to make the authentication work again.

I use it in ubuntu 17.10, but it will be logged out every time I reboot.

It gets deleted from Firefox too often.

Sorely lacking compared to Chrome. Main issue is the lack of a copy option for passwords. I use that all the time in Chrome for sites that don't autofill - now I have to edit the lastpass entry and copy from the password field manually.

It does not work in private browsing. My only option is to edit the password which requires making it visible and then use copy and paste. Real secure, people!

Features in the Firefox version of the add-on are lacking in comparison to the Chrome version. For instance, I cannot right-click on a page (or use the icon in the toolbar at the top) to copy my password so that I can paste it into a field that Lastpass cannot otherwise manage to auto-fill. Instead, I have to go into my vault and copy my password from there.

LastPass as a service is definitely 5 stars, the Firefox addon-- 3 stars as it currently stands.

Love this addon but with quantum update, i can't save username or password
every time browser closed and reopen, i have to re enter email again

Cannot copy password without reveling it.
In general, there is limited option in UI panel comparing to previous non web-extentioned addon.

These steps fixed all the issues I had around not being able to copy username/password without exposing it:

Why you you have to jump through these hoops to get full functionality is beyond me (hence 3 stars because this UX just sucks).

Otherwise, it works fine I guess.

まだ充分に理解出来てない為活用感なし。

The "key" to the issue is a combination of FF "private browsing mode" and the "clear cookies" setting. It seems that LP does not save any settings when the Private Browsing Mode function is checked. If you insist on this setting, forget the use of LP in FF, period, until they fix it.

However, when "Private Browsing" is unchecked and the "cookies" box is unchecked in the "Clear History When FireFox Closes > Settings", LP seems to operate with full functionality. If you can live with LP not launching the Log On page when you start the FF browser, you can leave "cookies"checked and log on to LP after you launch FF via the "add-on" icon. My LP log-on page launched with my UN saved and only asking for the master PW. After sign-on, LP launched the vault in my preferred view setting. Other functionality throughout the program remained.

So, here is the task for LasPass tech support:

1. Fix the LP program so it works in FF "Private Browsing" mode.
2. Fix the LP program so it works when FF is set to delete cookies when FF closes.
3. Fix LP to function when you enter the LP domain in the " Allow cookies from websites > exceptions" entry.
