[<script src="moz-extension://...averylong guid.../injectedPasswordless.js" type="text/javascript"></script>]

This script (without the brackets) is being added to my WordPress site Text Editor. I substituted the long string of numbers with the words ... a very long guid ...

I have contacted all developers of plugins for WordPress and now I realize it only happens when I edit my site in Firefox. It does not happen in Chrome or Safari, these 2 browsers do not produce this script. It also occurred to me that moz is short for Mozilla (not Moz the SEO expert).

If I only click into a text editor while editing my site the script is added to the text editor!! I have disabled most of my Firefox addons and it still happens. Please advise. What is this?

This is one of your addons. Disable everything and restart the browser.
