Password manager no longer appears in my firefox?

Hello ceg5143,

Welcome to the Community.

To start this with, please check if Trend Micro Password Manager is still installed on your computer. You may check that through Settings > Apps.

If it is not installed, you may follow the installation instructions here: Installing Password Manager

If Password Manager is already installed, you may try enabling or installing the Password Manager extension for your browser: Password Manager toolbar is missing from the browser 

I hope this helps!

Pat
