Brilliant when it works; otherwise, and often, a real pain. Example: something to do with "installing the binary version" that LP can never quite make clear to the thousands of users having similar problems. One of my support requests was answered by their advising me that I would have to enable passwords in FF for LP to remember my password for sign-in. Really? You want me to compromise my entire privacy approach? But is that even the real solution? Nobody knows and nobody seems able to get a clear solution from this company.

Also, a serious security concern when enabled in FF; even when not signed-in, LP is calling home. Best to disable it when not needing it.

Used to be a 4 or 5 star add-on, BUT in the last couple weeks I have constant connection or "unknown" errors when trying to save a login or update a login. Using LastPass 4.9 and Firefox 59.0.2 as of this writing. Ugh!

Firefox 52.7.3 not working. Thank you for correction.

Not working in Firefox 52.7.3

Doesn't work on Firefox for Android, and the Lastpass Android app doesn't work with Firefox for Android either. The only way to input passwords into Firefox is to copy them from the app.

When trying to login to this extension on Firefox for Android the page goes blank after selecting log in. Also when typing my email address in on the login page the input box keeps disappearing out of view and you have to keep dragging it back into the screen view.

Using the latest Firefox for Android and the same happens with the latest version of Nightly. Running Android 8.0 on Samsung S9.

Constantly logs me out, regardless of settings. Doesn't work on many sites, even sites where it used to work. Vault screen does not occupy the full browser screen. In general difficult to use and getting worse.

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.

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...

Can't fill Authentication popups. According to website, this functionality now only works on Chrome. Guess I'll be looking for a new Password Manager, darn it.

So far, so good.

I just started using the add-on, but something that is painful is that I have to manually import one by one my accounts from built-in password manager. the importing function does not work currently on Firefox 57 or up (Firefox quantum), so, if you have a really big key chain, that's something to keep in mind.

I want to copy my password

Frustrating experience when reporting specific issues with website.Seems that Lastpass should pay us fro reporting issues since it can take them 3 months to actually admit that yes there is an issue with Firefox version of Lastpass. Firefox version of the extension takes second fiddle with respect to the Chrome version. Reason why I stopped being a premium user of Lastpass was due to the Firefox version of the extension seemingly having problem after problem and it takes forever for support to actually admit there was an issue.

Works but used to be much better. Not able to easily copy password anymore without going to Edit Site... This disrupts many tasks such as using stored password in separate apps, terminal sessions, etc.

I got LastPass for the multiplatform support and sync but I'm seriously looking for alternatives by the time my current premium subscription runs out because of the declining Firefox support. How weird is it that you need the binary component for many of the basic features (copy username/password) of the extension to work but this is not mentioned anywhere in the description on this very extension page? I've been sticking with LastPass through the Quantum update waiting patiently for things to get better and I just found out about this.

This add-on is not up to par with the Chrome version and even the Edge version in some areas. The biggest missing feature is click on "Show Matching Sites" -> rt. click on the desired user name and get a context menu and be able to Copy Password.

I'm a long time paid user of LastPass. It has progressively become worse and worse over time. Offline access simply doesn't work and there are significant delays between logging in and the extension responding. In the meantime all that shows is a small unresponsive bubble, while CPU use shoots up. The Android app works maybe half the time for in-app logins. Disappointing.

Used to be really great, but lost a lot of functionality with the Quantum update.

Features such as Copy Username/Copy Password are missing and a lot of minor frustrating details such as the search bar not being highlighted when clicking the lastpass icon (you have to tab twice to get to it) or that you have to input your password twice in a row if not already logged in (didn't have to do this with the old plugin).

This coupled with the fact that it has become highly unreliable in saving passwords that it generates (I've resorted to copy/paste and opening sites in my vault to replace passwords).

It has just gone from a really smooth experience to being as cumbersome as having a standalone desktop application, which sometimes makes me wonder why I'm not using that instead :(

Works poorly on Firefox 57+: fails to auto-fill at least 40% of the time, and doesn't offer the option to copy username and password via context menu -- you have to manually open the vault entry in a new tab, un-blind the password, and copy-and-paste it over. This is very frustrating and I will unfortunately be sending me back to Chrome until this can be fixed for Firefox.

Used to work very well, but it's now more of a hinderance than a help. Am on Firefox 58 at work and it doesn't appear to work with any password that appear in pop up boxes (all work ones!) and doesn't remember the website when creating a log in on a new site etc.

There are so many workarounds I think it may be easier to go back to manually filling in the password myself.

You can't dismiss any notices this addon throws at you to actually get to its menu when you click the toolbar icon, and "never show me this again" doesn't work either. Poor port. Bit more effort?

The (lack of) responsiveness to fix this Firefox 57+ add-on is very bad.
I am considering to look for another password manager.

LastPass is significantly worse on Firefox (58.0.2) than Chrome, which is a real shame. The login dialog is usually too small to see the login form, though it has appeared correctly in the past. It's probably not a good security practice to enter your password into a form you can't actually see! Additionally, site search, when triggered by a hotkey, opens in a new tab, rather than in the dialog, which makes it a pretty big pain to actually use...

Please bring LastPass up to parity with Chrome for Firefox!
