I can't login on Firefox for Android : it just displays a blank page after you input the credentials

What I ask of LastPass is SECURITY above all...I'm not technical enough to know for certain that LastPass is the most secure option available. I have to trust reviews from people in the crypto/hacker/coding community, etc. who can analyze the code and/or hack the "system" and find vulnerabilities. From the research that I've done LastPass is a good option...the best that I've found.

Usability: LastPass is frustrating!! It doesn't do anything very well. When creating a new account it's weak. In my experience, most of the time it doesn't even "see" that you're singing up for a new account, so I have decided to open the LastPass Vault, click on the + (plus symbol) and create the account step-by-step. Even doing this is somewhat frustrating: right-clicking in the password field to generate a password forces you to mouse to the bottom of that dialog, click Generate Password and then mouse down to select Generate Password and then select your options.

MANY times I relied on LastPass to know that I am signing up for a new account and have regretted it because it either doesn't see/know what I've input into any of the fields and/or I have to go back to the site and select "Forgot Password" or whatever because LastPass effed up! Makes you feel like an idiot.

After LastPass has the correct user name(s) and password(s) in its database it still doesn't work most of the time for me. For example, I open a site and the logon dialog appears. My wife has one account and I have another account. LastPass often won't even recognize the site (the same URL that is in its database including what's after the slash, e.g. https://www.xyz.com/login).

Often LastPass will post and indicate that it recognizes the page you've loaded. I guess, you're supposed to be able to click on the LastPass icon and the login options are supposed to post (e..g. my wife's credentials and my credentials) and then click on one and it will enter your credentials. Most of the time I have to open the LastPass Vault and copy and paste the information back onto the login page.

Trying to login to leave this review took four times, i.e. my wife's credentials posted and my credentials posted. I selected my credentials three times and LastPass never entered them. I opened the vault and copy and pasted my user name and password.

Conclusion: if LastPass is as secure as the reviews I've read it's worth the frustration. But it would sure be convenient if LastPass actually worked as advertised on my devices (x3).

Unusable. Firefox 57 - LastPass main menu opens 2/3 cut off the right side of my screen. Can't navigate reliably. As others have said, no option to copy password.

Sometimes I need password only, but this version can't do it. I have to open the Edit > show password > copy it . And hopefully I don't change any settings when I just want to copy password. I don't know this problem is ONLY on Firefox version.

Very Good, Thanks

Convenient, works for the major part of required passwords, saves oodles of time.

Terrible. Doesn't auto-fill in username and password on sites that used to work. The copy username/pass feature has also been replaced by the silly More > Edit functionality. Every time I need a password now, I have to Edit, show the password, copy it, go back to the tab, paste, and close the Edit tab. Will be switching to another password manager if this isn't fixed. This is on Firefox 57.

The new 4.2.1.21a is not working poperly on Private Mode with FIrefox 57. Sometimes selecting the icon does not show the menu.
Also many fields are not being filled properly, I need to copy / paste to fill entries

This is one of the most easiest password managers I have found. I love it!
