Howdy,
This system is running Fedora 42 at the "latest" update level.
When I start Firefox I adjust the widget size on two instances of the browser. I use Firefox for a while and then exit Firefox. Upon a restart, I find that I have to, again, adjust the widget sizes.
This failure seems to happen when choosing "Maximize" from a pull-down menu from the very top of the Firefox widget but I have seen failures after manually resizing the widget(s).
Best regards,
George...
