User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:53.0) Gecko/20100101 Firefox/53.0 Build ID: 20170112030301 Steps to reproduce: Just normal browsing using Nightly. It might happen just after an Firefox update. It happens on any site, not just reddit. Actual results: Something appeared on top of the web content. If I drag it my finger on it, it seems to uncover itself. The only way to get rid of it is to close the tab and open a new one. https://imgur.com/a/fQpCt Expected results: No overlay should be on top of the web content.
Moving this to Graphics, Panning and Zooming component. If I'm wrong, please move it to the correct component.
We've had another bug reported on this same issue in the past, but it was never resolved. Marking this as a duplicate of that one.
It seems to be the same thing.
