See https://hacks.mozilla.org/2016/09/firefox-49-fixes-sites-designed-with-webkit-in-mind-and-more/ for more information, how to report the issue to Mozilla and how to disable the new "feature" in Firefox.

You're right, I just clicked the last reply button but it was intended for the thread starter.... Had you not responded, I could have deleted it and changed that

How would the lsl-client-bridge access an information you never type(d) in-world ? And even if you did type your password into public chat a thousand times, the viewer bridge will not even notice that. The viewer bridge uses an open source script that you can view at any time, and the script was not designed to listen to public chat, nor to process any of that. I don't know where you downloaded your third party viewer from, but whatever apparently stole your password, did not come from The Phoenix / Firestorm Project, and very likely not from any other viewer in the Third Party Viewer Directory either.
