The Last Pass password manager add-on for Firefox is definitely worthwhile. If you are someone who uses the same password for most of your sites and has a hard time coming up with passwords, Last Pass makes the experience seamless. When you create an account on a website, Lass Pass can be used to generate a strong password and then it saves the website for you so that you can easily login to the website whenever you want. The Firefox version is definitely better than the Edge version because it is easier to generate a password and fill it into the place it is needed. However, Last Pass for Edge may not save the generated password or update the password for your site if you changed it.

Twice in the last week LastPass has disappeared from my Firefox browser. Last Friday I was able to get it back with some difficulty. LastPass has disappeared again today (there was an update yesterday), and I CANNOT get it back now. I even completed removed the old version from my browser and tried to install it fresh from Mozilla's list of add-ons, but every time it tries to install I get message saying it could not be installed because Firefox could not modify the file. I don't want to switch permanently to Chrome, but I may have to.

just as broken as the beta was in Firefox for Android and LastPass don't care

Use LastPass 2 years. That's a great product, thanks so much for developers.

It has been my pleasure to use LastPass for quite some time now and I continue to appreciate the features, security and convenience it offers. This becomes particularly relevant as I grow older, the number of my passwords increases, and "Though my mind and body grow weak, God is all I need" remains more true than ever, I'm still happy to have LastPass to help out. :-)

Version 4.2.1.21 is the worst version ever. It doesn’t work properly. What a moron published it. It doesn’t fill properly half of sites. Especially the ones with popping login prompt, they even don’t have special icon for fill. An the suggestion to store password for completely different page than it’s inputted. Disaster. First Xmarks, now Last Pass. Both correlated products are useless now. And no fix on the way. Sorry but I’am looking for alternatives, after all the years.

Can't find any traces of active LastPass extension in browser. Can't use it.

Doesn't work on Firefox 57.0 Android. Shows blank page after login.

I was a long time lastpass user, you slow down my browser a lot and many options does not working. Auto fill password from green bar notification on some website it does not fill the correct password, I have to manually copy the password and fill myself.
Now, I move to bitwarden, it is a lot faster.
