i would love to have a way to disable favicon caching entirely and not only the option to manually clear it from the cache. i never close the browser so having a “clear on browser close” is not quite as helpful either, but would be a welcomed feature either way for many users and the rare case when you do close the browser.
every time a tab hibernates due to inactivity it would be nice to empty its cache and force a site reload to re-grab the favicon as well; but i dont know if tab hibernation is a native brave feature or an extension.
