Hi, where is this showing up -- on website forms?

I don't know whether Firefox Relay involves an add-on, but you can look for it on the Add-ons page. Either:

• Ctrl+Shift+a (Mac: Command+Shift+a)
• "3-bar" menu button (or Tools menu) > Add-ons
• type or paste about:addons in the address bar and press Enter/Return

In the left column of the Add-ons page, click Extensions. On the right side, find the "Manage Your Extensions" heading.

Then cast a critical eye over the list below that heading. Anything that seems to be related to Firefox Relay?

While you're here, check for anything suspicious or that you just do not remember installing or why. Any extensions Firefox installs for built-in features are hidden from this page, so everything listed here is your choice (and your responsibility) to manage. If in doubt, disable (or remove). For your privacy and security, don't let mystery programs linger here.

Any progress so far?

Solved. Thanks. Curious because I didn't install this addon. It seemed to show up with v.97 update.
