I have the Add-On/Extension active for all my browswers (Firefox, Chrome, & Edge) and am very pleased with it, when it works properly. Rating it 4-starts for two reasons. The only annoyance I have experienced is when the mobile unlock connection isn't working properly.

Second reason is that I wish the Add-On had Password Generator functionality for changing of existing passwords (in the Edit logon dialogue) - I only see this functionality in the mobile app.

Otherwise, would rate it 5-starts. It's a very useful tool.

Constant issues with long-running scripts with "Unresponsive Script Warning). I have unistalled and reinstalled but problem continues. Not compatible with FireFox.

Generally NPM is very good, but it had one annoying problem that has caused me to stop using it and go back to LastPass. NPM has an all-or-nothing attitude; prompt to save all logins, or do not prompt at all. There are some logins which I *never* want to save, yet NPM keeps prompting me to save them. It would be nice if NPM let me specific not to save logins for certain websites. Until then, the constant prompts are too annoying for me to use NPM.

Whatever script is running on this extension is causing sites to be extremely slow. Uninstall the extension, and sites run smooth. So, Norton, figure out the script and work on it because you're extension is currently a burden on the system.

Simple, easy to use and effective, if you keep it up to date. If you have it running, it will ask if you want to update passwords as you change them and use the site again. But you have to remember the password when you change or open the password manager to change it.
