LastPass Import Issues – Troubleshooting Import Feature on Firefox

firefox-extensionsimportlastpass

I'm trying to get LastPass to import my passwords in a CSV file exported from Avast Passwords. For some strange reason, the option to import passwords doesn't seem to work. The screenshots below showcase the issue I'm currently having.

When I press "Other", nothing happens. I've scoured the Internet for a solution. I do have BinaryComponent set to true. I have also clicked on the "Firefox Password Manager" option, it doesn't work.

Apparently, that button doesn't work so I found another way to access the Import button:

I also logged out and logged back in again, that may help.

Encryption – How LastPass Stores Your Passwords Securely

All encryption/decryption occurs on your computer, not on our servers. This means that your sensitive data does not travel over the Internet and it never touches our servers, only the encrypted data does.

[...]

Your encryption key is created from your email address and Master Password. Your Master Password is never sent to LastPass, only a one-way hash of your password when authenticating, which means that the components that make up your key remain local. This is why it is very important to remember your LastPass Master Password; we do not know it and without it your encrypted data is meaningless. LastPass also offers advanced security options that let you add more layers of protection.

In other words, your computer encrypts your passwords with your email and master password and sends that data to Lastpass. When you authenticate with your master password at Lastpass.com, Lastpass.com returns all your encrypted passwords, which are decrypted locally on your computer with your email and master password. Every communication happens over SSL, so anything intercepted is doubly useless (since everything is encrypted with not just the SSL keys but with your email and master password).

The best way to ensure this is to set up a script to monitor network activity and see if anything that is decrypted (including the master password) goes to lastpass.com. Based on what I've seen on forums, it seems other users have done this and found nothing suspicious.

Firefox on other platforms utilizes the Firefox profile directory. You can back these directories up and they will contain the latest copy of your data. Be aware that on Windows, Protected Storage is used to additionally encrypt your data so you'll need to ensure that your Windows profile is also backed up. Your data is also backed up at LastPass.com, and a copy is on any other device or computer you use so this isn't required.

Your data is also securely synced with the LastPass servers. When you make updates to your LastPass account, whether in a browser plugin, a mobile app, or the website, the updates are reflected on the LastPass servers as well. If your hard drive ever crashes, or your laptop is stolen, you can easily regain access to your accounts by reinstalling the plugin (https://lastpass.com/download.php) and logging in with the same email and master password.
