Hi,

I am unable to replicate this since i dont have anymore my HBO Go account.

please download Firefox Nightly from here: https://nightly.mozilla.org/ and retest the problem to see if its already fixed.

If you still have the issue please create a new profile, you have the steps here:https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?redirectlocale=en-US&redirectslug=Managing-profiles#w_starting-the-profile-manager

Lastly test if the issue is reproducible in safe mode, here is a link that can help you:

I can reproduce it on the latest Nightly on macOS too and it moves when the mouse pointer hovers on it. Looks like a toolkit issue?

Hello,

I’ve also attempted to reproduce the issue on the latest Nightly, Beta and Release using HBO Go on Windows 10 Pro 64-bit and Ubuntu 16.04 LTS, however without success. No URL is visible at the bottom while in fullscreen.

I am not sure that testing using HBO Go is relevant to this bug, as you stated you were using HBO Now, however, since they both deal with video streaming and come from the same provider, I tried it with what I had available. The conclusion is though, that with HBO Go the issue does not occur, at least on my end.
