Does not work on Firefox Mobile. Found this on their forums:

"Hello All -

We’ve made the decision to retire LastPass for Firefox Mobile (only available to Android users) on January 31, 2018. If you are currently using this version, you can continue to use it but you will not receive any feature or security updates. Moving forward, LastPass is committed to supporting the Android platform through the new Android Oreo autofill API, as well as the original accessibility autofill service. In the short term, we recommend you use another Android browser, such as Firefox Focus or Google Chrome.

The LastPass Team"

Why do you need all of these privileges? If so, why not explain? Couldn't you do this add on with lesser privileges? At least explain why you needed such daunting access.

Lastpass used to be a great tool, however, it has gone from bad to worse lately. May autofill on sites or it may not. Continues to log out randomly after closing the browser or when clicking on a new tab. These people should be ashamed of themselves, this is a common and long-standing complaint but they do nothing.

Cannot add extension or whatever it is is that puts on icon on my Firefox. I'm having to create a new Last Pass account and remove my original LastPass account as I am a victim of hacking. Now I cannot get the LastPass icon on Firefox.

Does not work on Firefox Android

以前这个扩展还不错，现在已经无法正常使用了，根本打不开，也不知道天天更新的啥玩意

Perfect for desktop, useless for mobile. On Firefox for Android extension I can't log in after writing the password, I waited and waited yet it doesn't do anything.

Used to be great, but for some reason it is now missing a load of features that the Chrome extension seems to have. The autofill fails now and then, copying your password manually is way too hard and should be available within 2 clicks.

Does not work since the lastest minor version 4.16.x. I set Firefox to never remember history and the LastPass refuses to work. Downgraded to previous minor version 4.15.x, but if this keeps up, I may have to consider switching to another password manager.

Ervaring was aanvankelijk positief maar veranderde plots. Kreeg steeds bij het opstarten van Firefox een scherm met "u bent er bijna", klik op, dat weet ik niet meer. En niet weg te krijgen. Heb op den duur Last Pass dan maar gecanceld. Zeer tegen mijn zin, toegegeven.
Eergisteren, gisteren, vandaag probeer ik LastPass voor Firefox opnieuw te installeren. Boter aan de galg: ik neem aan dat ik een nieuw account zou moeten maken. Krijg in de plaats steeds opnieuw een venster met "e-mail adres reeds in gebruik". Wachtwoord van maanden geleden is natuurlijk niet meer geldig, maar een nieuw generen? Gaat niet. Ik ben 77 jaar maar zo'n boeltje heb ik nooit meegemaakt. Als de beveiliging van de wachtwoorden even rommelig is staan we er slecht voor.

can't even show login window. disaster.

LastPass has been in decline for the last year, and latest updates just take it from bad to worse.

- Latest version it is impossible to login to the extension. You must visit lastpass.com to even get the plugin to accept the login.
- Preference settings repeatedly do not save. I hope you like the defaults because you can't change them.
- Often the plugin menu itself will not even open if I need to login to a site. I have to open a new tab, then open the menu, and copy/paste the password out manually.

This extension is junk. My company standardized on LastPass about 5 years ago and it didn't suck so much then. Now I think we made a mistake and would not recommend this service to anyone.

I used to love this extension. I loved it so much that it was the only reason why I switched back from Chromium to Firefox. However since then it's becoming worse and worse. First Firefox quantum got there which made this extension utterly useless. I could understand that the developers needed time to update but it's almost 8 month now and nothing got better. It's even worse.
First the copy username/password buttons disappeared and were re-added last week. However they still does not work !!!
The autofilll is now way worse and does not fill anything or use wrong credentials.
And with last update the fault keeps opening randomly IN MY CURRENT TAB!
This extension is utterly useless. And i must say that it's really hard to trust a company with my passwords when their browser extensions are so badly made.

Garbage. Installed 4.16.1.1 on FF ESR-60 on Linux and no extension icon - have to use website login to access vault. Sort your testing out lastpass, this product is not fit for release.

Not working to copy/paste the credentials manually without the desktop app. Rubish

created a firefox account specifically to write this: Lastpass add on sucks.

I've used it for years, telling my friends to use it, but it has consistently sucked for the past few months.
I'm using 1password at work and it is miles ahead in terms of reliability.
Lastpass addon will often fail to autofill, or fail to save a new password when creating an account (it just did right now for my firefox account, I had to create it manually).
Save your time and use another of the many competitors.

Will not work correctly after getting updated to WebExtension plugin. Some websites do not get filled with credentials, and there are no buttons to just copy/paste the credentials manually.

Lastpass really sucks!!! In Firefox when you click on the add-on, you have to right click to open lastpass on their website. Then when you login you can't even put in a preference for the friggin thing to stay in list view or grid view or to keep the folders closed. When you launch one of the websites in your list, the friggin thing doesn't even insert the username and password; you have to do that friggin manually. There are a lot better password managers out there. Don't waste your time with lastpass!!!

18 attempts to create an account and be able to login = 18 failures!

bug :(
