Goal of Feature, what is trying to be achieved (problem solved, use cases, etc)
- Multiple monitors lose fullscreen on focus change
- video full screen in one monitor and work on something else on the other
- or have 2 monitors have different things full screen
- Current plan is to show the full-screen warning again for 4 seconds whenever a full-screen page regains focus.
Mac Spaces questions
- Will this allow you to use multiple spaces on a single monitor? (With one in full-screen mode and another showing another app, or another Firefox tab)
- Probably? might need to ask zpao.
- With multiple monitors, mac's concept of spaces and full-screen tends to affect all monitors at once
What solutions/approaches were considered other than the proposed solution?
- Showing the warning again for 4 seconds upon return seems like overkill.
- How about just one second?
- How about a smaller warning? (Perhaps a watermark, if we can make it hard to hide)
Why was this solution chosen?

Any security threats already considered in the design and why?

Threat Brainstorming
- The "warning when switching between two full-screen windows" might be defeatable, when a single site is full-screen in both windows (immersive demos and games)
- What if a web page lies about where focus is?
- It can't prevent mouse clicks
- Lies about where the mouse cursor is?
- It can't prevent mouse clicks
- This isn't really worse than the situation with one full-screen window
