Reproduced using latest Nightly 34.0a1 STR: 1. Open Firefox 2. Set media.getusermedia.screensharing.enabled to true 3. Open http://queze.net/goinfre/ff_gum_test.html in a new tab 4. Click Audio & Video 5. Click Share Selected Devices 6. Move the taskbar from down to UP Expected result: The indicator stays above the taskbar and it can be accessed. Actual result: The indicator stays under the taskbar and it can`t be accessed. Notes: 1. This is Windows only, I did not manage to move the 'taskbar' on ubuntu. 2.

(In reply to Bogdan Maris, QA [:bogdan_maris] from comment #0) > 1. This is Windows only, I did not manage to move the 'taskbar' on ubuntu. bug 1041675 seems the Linux equivalent. I wonder if the solution here wouldn't be to use screen.availTop instead of 0 when positioning the indicator.

Comment on attachment 8474499 [details] [diff] [review] Display the window at y=availTop instead of 0 Seems ok. Is there a reason the popup is locked vertically? You might consider removing all the custom window dragging code and just using WindowDraggingUtils.jsm

Hi Florian, can you provide a point value and if the bug should be marked as [qa+] or [qa-].

Verified that if a call is made with taskbar on top it the global indicator will show under the taskbar not behind it. Tested on Windows 7 64bit and Windows 8.1 Microsoft Surface PRO, using latest Nightly 34.0a1.

Comment on attachment 8474499 [details] [diff] [review] Display the window at y=availTop instead of 0 Approval Request Comment [Feature/regressing bug #]: bug 1037408 [User impact if declined]: Windows users with the taskbar at the top of the screen may be unable to use the global webrtc sharing indicator that would be covered by the task bar. [Describe test coverage new/current, TBPL]: currently on m-c, verified by QA. [Risks and why]: Low, tiny self-contained code change. [String/UUID change made/needed]: none.

Also verified this using latest Aurora 33.0a2 on Windows 7 64bit and Windows 8.1 Microsoft Surface Pro.
