[Performance] the favicon no cache on firefox

[jqtmviyu]

Thanks a lot ! This extention work well on chrome.
But on firefox, the favicon refetch everytime and no use cache like it work on chrome.

If there isn't a robust caching solution available, opting for local resources might be a preferable choice, especially for performance reasons, as it allows for faster resource loading. At the very least, this approach won't adversely impact the user experience.(Or provide a switch)

This is the icon inside the Firefox browser: chrome://mozapps/skin/extensions/category-sitepermission.svg

::-webkit-scrollbar not work on firefox.

use scrollbar-width: none; instead ::-webkit-scrollbar { width: 0px; }.
