The extension works "well", but I miss some features and shortcuts like "copy password" and other from the dropdown menu when I click on the widget icon that are available on chrome/opera versions.

YA

Doesn't work. Won't log in at all. Simply amazing how LastPass releases non-functional software like this.

Works most times, but auto-fill does not work + it still remembered old password after I've updated. Waiting for an update

Will not complete login on latest Firefox (Android). Can't use it.

Seriously, such a regression for FF Quantum is not acceptable. It has been months or even years old APIs were deprecated. With the current set of features, the extension is cumbersome and not useful. Where is auto fulfill and copy username/password. Having to go on the site -> EDIT -> Show password -> Select -> Copy -> Paster somewhere else, the workflow is really crazy..

The most consistent inconsistent pail of garbage one can be forced to eat out of. Just ONCE, even after re-installing and updating Firefox, would be nice if Last Pass could auto fill and log into my two email addresses. My blood pressure and gray hair plead with me to abandon this JOKE of an add on!

It stopped functioning properly some time ago. It does not log out automatically, it is not able to fill usernames and passwords, it loses newly generated passwords frequently, not able to save new sites, etc., etc. This add on is a piece of junk.

With the current bugs (constant re-authentication, no copying username/password, no auto-fill) this extension is useless for me. Due to missing Firefox 57 support of this and other addons I have kept Firefox 54 for now with all auto-updating disabled. For all those in the same boat who want to also revert the LP extension back to a working version, here's the link:

This has been a very useful add-on, and now that LastPass has become a web extension, the incompatibility with FF57 is over. Thanks for that. BUT, the web extension lack the very useful "copy username" and "copy password" features! The user now has to open the Edit page for a website, unhide the password field, and then copy the password. That's not useful at all! Please fix this. ALSO, LastPass doesn't offer to save a newly registered site. The user has to manually save a page in the Vault.

Fixing these could bring back the good old shine to LastPass again!

It just lack the most important features... Just copying a simple password is impossible without opening the edit window, we can't fill password on HTTP basic auth window any more, etc, etc :'(

扱うサイトが多く細かいパスワードを覚えずにすむので重宝しています。

too many problems with lastpass for firefox.

super easy. generate secure passwords, never feel lost with last pass.

very good
