Some big issues in recent months on Firefox.
1) Sites with pop-up windows are not recognized by LastPass, so I finally figured out I need to right-click and use Autofill, which works most, but not all, of the time. A pain.
2) On some sites, you enter a new login and password, but for some reason, LastPass doesn't detect this, and then you have to enter the login manually in LastPass. More of a pain.
3) I saved the best for last. As others have reported, if you keep Firefox open for too long, the add-on stops working. It's most annmoying when you are trying to add or update a password and LastPass just keeps timing out. Your choices now are to either reboot the browser, or add the password manually. Aaaargh! Biggest pain of all.

I figure these are all Quantum issues, but how long do we wait before this is fixed? I remember the good old days (early last year) when LastPass just worked!

Greatest password manager I have ever used, even better than the paid ones.

Awesome program. Took a little time to wrap my head around relinquishing control but well worth it.

It's buggy, if you log out leave browser open go to log in again, it quite often hangs so you need to restart the browser, when the browser reopens you are magically logged in. It’s like there is a refreshing issue. It’s a shame, I’m still stuck with chrome until this is fixed!

do dupy

It is failing to keep up. Limited browser support and what would be cool features if half of them worked. LastPass isn't enough to make me want to switch browsers and the other options get better and better.

This addon is a waste of time. Select a saved login and it goes blank. Attempts to auto-login after attempting to enter an alternative login erroring out the account. Some pages aren't recognised at all (ie. ebay). It's more of a hindrance than a solution most of the time.

the best

I feel secure using it's generated passwords and the convenience of the automatic logging in. But must admit I liked the original version much better.

can't import from firefox (58.0.1 (64-bit)) !!

It is not open source so how you can trust it to sync passwords or even offline use

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 :(

This is huge bonus for me, don't have worry about slow sign in's and gets what i like alot faster, Thank You to Firefox for this addon and everything else you do for me, Thank You.

Significantly reduced functionality pre-Quantum or Chrome.
I reported it months ago and was directed to beta which is hard to find.
And now I notice that many people complain. It feels like they want to drive people to Chrome.
Unfortunately it's working.
I am upset with myself, I should abandon LastPass

Easy to use and works well across platforms
