That's the default content setting.

Desktop -> chrome://settings/content/notifications
Android -> Site Settings > Notifications

The top-level toggle in ON state means "Ask by default", OFF means "block by default".

Ah, nice, thanks.

IMHO this option could be better name, i.e. "Ask before accessing (recommended)"/"Block" isn't very clear. Something along the lines of "Ask for each site by default" / "Block all sites by default" would be better. Not sure if it has a better name in other languages, but it would probably not hurt to have those reviewed by the i18n/translation team as well.

This settings page is also not very discoverable, i.e. "Content settings", which is found in the advanced settings on the chrome://settings/, is not an obvious name to search for permissions and site settings. At the very least, we could highlight the "Content settings" settings when searching for "permissions" and/or "site settings" in the search field above.

OTH searching for individual permission names such as "location" or "notifications" does highlight "Content settings", so perhaps I was just now trying hard enough. Still adding "permissions" and "site settings" would probably help other people looking for this setting.

Hmm, I thought we were going to rename it to "Site settings" on Desktop as well in M69.

And the chrome://settings/content/siteDetails should perhaps also have a way to reach the default settings.
