hello,
I have the same annoying issue with the latest Firefox and latest Joomla! 4 and on Mac. It works more or less on Chrome and Vivaldi. This camera icon just doesn't work well. It is too sensitive. A least I found out, with the right mouse click beside the icon, it is possible to add a new picture. It would be great add an icon for each tasks, and not a single icon... this Galley great but really expect this camera icon to add new pictures.
