New UI is Crap Rated 2 out of 5 stars

Switching from Chrome to Firefox. In Chrome you could toggle the older interface, on Firefox's LastPass you can't.

LastPass, your new UI is complete crap. It is not designed for a desktop. This isn't Android. Redo it.

Horrible Performance Rated 1 out of 5 stars

How does this get so many good reviews? I may have corrupted some settings in Firefox somehow, but I get horrible performance in Firefox when I have this add-on enabled.

Love it! Rated 5 out of 5 stars

I've never written a review for an Add-on, but Lastpass has changed my life. That's not even an exaggeration. The Firefox Add-on works as promised for me, and adds to the seamless integration of convenient password management across devices. Thanks for a great product Lastpass!

No electrolysis support and about:performance indicates that LastPass is severely slowing down Firefox

Had to stop using. No electrolysis support. Rated 1 out of 5 stars

No electrolysis support = goodbye.

With E10s enabled, it constantly freezes, doesn't connect to the servers.

Nope Rated 1 out of 5 stars

Support is useless with their canned robotic auto responses and although they have a forum for feature requests, it's just giving false hope and they don't actually care.

Why the heck is dealing with ports like not native? Because it's badly written, that's why.

Old and dated Rated 2 out of 5 stars

This addon looks very old and dated. The hover menus often appear in the wrong place (across the screen) and sometimes doesn't work at all. Even things like viewing the sites just opens a blank page and sits there saying its waiting for the page to load.

slow down the browser Rated 3 out of 5 stars

It took me a while before finding out that this addon is the culprit for slowing down the entire browser which needless to say I'm deeply disappointed.
PS:V4 is much better, strongly suggesting using dev channel

Indispensable! Rated 5 out of 5 stars

Siempre que he de instalar Firefox en un nuevo PC, mi primer complemento es Lastpass seguido de Xmarks. Excelentes e indispensables los dos.

Outdated Rated 4 out of 5 stars

I love the LastPass BUT the version on mozilla is outdated. LastPass 4 is out and you should get it from the official LastPass website.

Plz sign this app Rated 1 out of 5 stars

Why the heck this app doesn't get signed? I hv to look for a replacement then.
Even Keepass&Firefox is broken.
I better look for a replacement for Firefox.

huge memeory leak with version 4 Rated 1 out of 5 stars

i want version 3 back now. version 4 is eating my ram

Was great 5 stars but Rated 2 out of 5 stars

its rapidly becoming more of hinderance than a help. So many sites aren't syncing with Lastpass.
- Lastpass you need to sort it out...

Performance impact Rated 1 out of 5 stars

And I suspect the developers of this extension is using socks puppet to vote their own extension with 5 stars.

Advanced Options Keep Dissapearing Rated 3 out of 5 stars

Used Last pass for a long time but I am getting frustrated with version 4.1.5a in Mozilla. The advanced options keep disappearing after awhile and I have to keep removing it and reinstalling it.

The advanced options are so you can control auto logon and auto fill. The up and down arrow shows nothing in Mozilla only. The options will not show. Works perfect in Google Chrome. Seems like a Mozilla problem to me.

Broken Under Firefox 46.0 Rated 1 out of 5 stars

The add-in appears to be disabled. I cannot get it to open vault, or access date.

Excellent! Rated 5 out of 5 stars

Excellent addon, I use it all the time. I've been with LP for about 2 and a half years! I use Firefox and Chrome browsers. My only negative thing is that LP do not seem to have updated this in ages unlike the Chrome addon. Come on LP, update it please :)

This addon barely works, and will absolutely destroy your Firefox performance Rated 1 out of 5 stars

This addon is simply broken. 90% of the time it just doesn't work - passwords are not filled in, the LastPass buttons do not do anything, and searching for passwords yields no results. I've recently switched from Chrome to Firefox, so it seems clear in comparison the Firefox addon is lacking in attention from the developer.

Not only does the addon not work though regards its core function of managing/filling in passwords - it also completely destroyed my performance on Firefox. Pages began to load with a delay, and the browser itself seemed more sluggish. Had to rule out each addon I had installed one-by-one until I found LastPass was the definite culprit.

I would urge you to avoid the LastPass Firefox addon. Instead consider the open source KeePass (if on Windows), or for an alternate proprietary option consider 1Password (which has an excellent Firefox addon).

LastPass Premium does not install with Firefox 45.0.2 Rated 1 out of 5 stars

I've spent reinstalling the app on Firefox. Did a fresh install, etc. I can't believe how much time I've wasted. The extension does not install. Even after messing with the allow restrictions etc.
