Fullscreen Cursor Hider von GryphonTools

Fullscreen Cursor Hider automatically hides the mouse cursor on webpages when Firefox enters fullscreen mode and restores it when fullscreen ends.

It works with Firefox's F11 browser fullscreen as well as webpage and video fullscreen modes.

The extension has no settings, no tracking, no analytics, and does not collect or transmit any data.

The extension needs access to webpages only to apply the hidden-cursor style. It does not read, store, or transmit webpage content.
