Does not work when in fullscreen mode when in firefox

When you have desaturate all active, it works for cases.

In firefox, when you play a youtube video in fullscreen mode the overlay is not being applied anymore.
the program does work on chrome when in fullscreen mode.

Can’t confirm, works fine for me with Ubuntu 18.04.2 LTS, GNOME 3.28.2, Firefox 66, and current extension version from GNOME Extensions.

Extension stops working in firefox after some period of time, approximately after one hour.

Similar for me, for any page going into fullscreen mode the effect suddenly deactivates after a couble of minutes, reenters when I go windowed, and instantly deactivates if in fullscreen again. Turning the add-on off and on again does not fix the problem.If you want, I can make a video depicting the problem.

Pretty sure this repo isn't maintained any more. I don't see this behaviour with Firefox, but I do with Kitty.

FWIW, this extension effectively just calls code from https://gitlab.gnome.org/GNOME/clutter/-/blob/master/clutter/clutter-desaturate-effect.c which is doing OpenGL stuff, I guess GNOME hands over control to applications when they go fullscreen or something? I also note that Redshift remains applied when I fullscreen Kitty.
