User reviews
Pros
- Effectively enables fullscreen video playback within the browser window without true fullscreen mode.
- Works well on popular platforms like YouTube and ESPN+.
- Simple and straightforward functionality that 'just works' in many cases.
- Helpful for users wanting to expand video size without switching to exclusive fullscreen mode.
- Safe and trustworthy based on source code review.
Cons
- Sometimes fails to detect or work with videos on certain websites, especially embedded videos or niche sites.
- Buggy behavior on some platforms like Twitter where video pauses or is cropped.
- Replaces website's native video player with a generic Firefox player, occasionally inferior.
- Lacks options to select among multiple videos on a page or integrated right-click menu for easier selection.
- Requires manual focusing on the video player for hotkeys to function properly.
Recent reviews
Works nicely! I wish there was an option to select the correct video in case there are multiple videos on the site. Maybe adding to the right click menu of the videos would be possible?

Extension safety
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk
impact extension cannot do much harms, whereas a high risk impact extension can do a lot of
damage like stealing your password, bypassing your security settings, and accessing your
personal data. High risk impact extensions are not necessarily malicious. However, if they
do turn malicious, they can be very harmful.
windowed-fullscreen-video does not require any sensitive permissions.
Risk impact analysis details
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious.
This is determined by the publisher and the Firefox add-on reputation on
Firefox Browser Add-ons, the amount of time the Firefox add-on has been
around, and other signals about the
Firefox add-on. Our algorithms are not perfect, and are subject to change
as we discover new ways to detect malicious extensions. We recommend that you always
exercise caution when installing a Firefox add-on.
