Background fullscreen video overlaps taskbar

more options

https://i.redd.it/73wcc6kmmbb11.png As you can see here, I have opened reddit and new window with fullscreen youtube at background which overlaps my taskbar at bottom. TechLaden from reddit told me: "This sounds more like a graphics driver issue than a Firefox specific one.

   Are your drivers up to date?
   Does this happen on other browsers or apps?"

I answered:

   "Not newest, but not old (current 398.36 and I have 397.93)
   Nope. I recently switched from chrome and got used to watch serials in that way, haven't any issues in it

I have notebook with integrated intel HD 4000 and GT 650, maybe problem somehow related to this?"

Also, I've tried to update my drivers, disabling hardware acceleration, starting firefox w/o addons - nothing worked.

This is the intended behavior for the Firefox browser and is not an issue that people on this forum will be able to solve for you.

The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers.

If you want to leave feedback for Firefox developers, you can go to the Firefox Help menu and select Submit Feedback... or use this link. Your feedback gets collected by a team of people who read it and gather data about the most common issues.

I hope I've read your question correctly. You have a YouTube video playing in fullscreen and open Firefox without minimizing the fullscreen YouTube video?

If that's the case, that's the intended behavior. Because you have not exiting fullscreen on the YouTube video, it will remain open in the background. The Firefox window will simply open on top of the YouTube video. Because the YouTube video is still in fullscreen mode, the taskbar is not visible.

You have to exit YouTube fullscreen videos in order to see your taskbar.

Yes, you're correct. I recently switched from chrome and I haven't any issues with that.

And also on reddit people says that this is not expected behavior, that they see taskbar. Some gifs: Here how it looks on chrome, and here, firefox.

Also I've notice just now this thing - explorer at background overlaps taskbar if I have firefox window as active.

And yeah, I'm not using nightly - it's just an icon :)
