"This extension will only work if you have the Sticky Password application already installed on your computer" - that means it works only on my home pc. so it's useless. for my office pc, for instance.

When it works, it's fine, but eventually it will grey out and no longer function. Full uninstalls, re-installs, restarts, updates, etc. don't fix it at which point it's useless and frustrating. The app still works, but auto-fill won't. MacOS + Firefox.
