Does that mean no extensions and thus no ad blocker? If so, do they have another ad block solution at the device level?

Epiphany has support for Easylist-based adblocking -- at least on the desktop version, I don't know about the mobile interface.

There's no distinction between the "desktop" and "mobile" versions of GNOME Web. It's literally the same code (compiled for the appropriate processor architecture), just at a different window size.

[Mediterraneo10]

Since I am personally unfamiliar with GNOME’s toolchain for compiling apps for both mobile and desktop, I didn’t want to speak too confidently about the matter above.

So, all options shown in the preferences of the desktop version will automatically be shown in the preferences of the mobile version?

You can test it by shrinking the Epiphany's window while running its latest version on desktop.

Epiphany has a built-in adblocker (using normal adblock style rules).
