tldr: It can be really useful but also super frustrating when you run into bugs.

This service is a blessing and a curse. When things go well, I love it. It makes everything a breeze. I know that my passwords are much more secure, and it is well worth the price.

On the other hand, when things go poorly, and it doesn't save the password, and then deletes it from your clipboard at a really crucial moment, it can be really frustrating. While that can be avoided by being extra cautious and while I was able to eventually find the history of recently generated passwords, it can still cause a ton of frustration.

Another big issue is when the extension occasionally bricks the entire browser for up to a minute. When the icon is yellow, I avoid clicking it like the plague.

With these factors, I came to the conclusion of a 3.

not loading in latest firefox

Used to work great, now it wont load or fill in anything

The fill just outright doesn't work today for me.

安卓手机Firefox浏览器的扩展无法登录！

How to set the language?I'm Chinese,not used to reading English.If you tell me,I'll give you good reviews.

Somewhat cumbersome with an iPhone. Will be adding the Safari extension to the phone and will re-evaluate if this resolves the issues. Big problem has been no cut and paste between my LastPass and other apps (safari and others). I find the LastPass browser overkill and usually avoid it unless I am going to a financial institution website. I love the Vault especially the ability to put notes on old passwords in the notes section:-)

It seems to be impossible to change your email address if your old address is no longer working!

Mostly works well (at least with Chrome) but I am having trouble with the extension in Firefox. I suspect I have a mis-configuration, but the extension works straight away in other browsers. I've had Lastpass for about 10 years now but I'm not a big fan of the version 4 UI and I don't know what they are doing with the premium subscription money I give them each month given that their internal search algorithm is absolutely horrible.

The password manager in itself is very nice and free accounts get plenty of features however support for this Firefox extension has been dropping off and it's not very usable anymore. Poor performance, glitches everywhere and no pin lock.

Used to be great, but as of late it has been really bad. Often hangs and doesn't allow me to enter my password reprompt so I have to keep re-installing it.
