To add some more info, I'm using Debian 12 and Firefox 132.0 (Flatpak version). I used Gnome's Screencast to record the clip but for some reason, I couldn't get the mouse/pointer to show up in the video even though I had "Show Pointer" enabled.

Last but not least, since my username appears on the video and I don't want anyone to get the wrong idea: I moderate a community called c/kickasswomen and everyone whose content is posted on that community has given me their permission—I don't steal anyone's content nor do I post anything without their consent.
