8chan features script
There have been some errors with saved settings after changing there structure with updates from an older version.
Update to the latest version and use localStorage.removeItem('fullchan-x-settings'); in the browser console (12 or inspect).
That worked, thanks.
Firefox 137.0.2
From 1.12.6 to 1.13.2 breaks the top bar and a footer. Gallery and setting don't work.
1.13.2 gallery appears but at the bottom of page along with some other elements.
