When changing the default settings of a game, and saving your changes, Firefox gets confused and asks if you want to leave the page without saving. Which is the exact opposite of what the user is actually doing. Specifically I'm talking about changing your game settings like this: When you click the "Save Defaults" button at the bottom, you get a prompt like this: You have to click "Leave page" to successfully save your changes, which is very confusing. If you click "Stay on page" then not only do your changes not get saved, but the "Save Defaults" button can't be clicked again because it has been replaced by a "Saving Defaults" button that is unclickable. This makes it impossible to then save your changes, and causes the user to lose all changes they've made. Something must be set up wrong in the Game Settings page's code or whatever. The same problem does NOT happen for the other similar blue buttons on the page like "Save Compendium Changes" or the "Save Changes" button at the very button. I'm using Firefox 90.0.2 (64-bit) for Windows 10.
