Can you post a screenshot of it?

The "1.00" is in the center of the screen. If I place the mouse cursor in the right spot (say over the right most zero), after a few seconds the mouse cursor changes to a hand and a few controls are displayed: << - + >> x I can drag the group of controls off to one side of the screen. I cannot actually use the controls, because as soon as I move the mouse off "1.00", the controls disappear.

I would like some way to prevent the "1.00" from ever appearing on my screen, much like the way using media.hardwaremediakeys.enabled set to False prevents the volume overlay from appearing.

Can you inspect this 1.00 text in the Inspector via the right-click context menu ?

• https://firefox-source-docs.mozilla.org/devtools-user/page_inspector/how_to/examine_and_edit_html/

If I right-click on the "1.00" text, it gives me the same exact menu as anywhere else on the screen. (If I wait long enough that the mouse cursor changes to the hand, right clicking does nothing.)

If I right-click and select "View Page Source", I enough HTML that is too long to post all of via this interface. Below is the start of it.

OK, I figured out that you want me to use the "Inspect" menu item. Doing an inspect via right click on the "1.00" and elsewhere on the screen seems to give me exactly the same results, so I don't think I'm getting information about the "1.00" thing, but the screen in general. Here is a screen shot of the inspect results for the "1.00" thing.

OK, digging into the inspect results, I think I've found the relevant code for the "1.00" thing.

     <div class="vsc-controller"></div>
       #shadow-root (open)
        <style>
          @import "moz-extension://9c6abd4e-0e00-456b-a9ad-467cba402d87/shadow.css";
        </style>
        <div id="controller" style="top:367px; left:762px; opacity:0.3">
          <span data-action="drag" class="draggable">1.00</span>
          <span id="controls">
            <button data-action="rewind" class="rw">«</button>
            <button data-action="slower">−</button>
            <button data-action="faster">+</button>
            <button data-action="advance" class="rw">»</button>
            <button data-action="display" class="hideButton">×</button>
          </span>
        </div>

Since the interface seems to have eaten some of the HTML code (above), here is a screen shot.

Hurrah! I got rid of the stupid thing. It turns out that the control is the "Video Speed Controller" and it is Firefox add on. I don't know how I ever got it - I generally don't add optional things (other than add blocking). Removing the add on got rid of the control. Good riddance.

Thanks, that was very helpful. It looks like it came from some extension.

Too late, u figured it out by yourself :)
