Hi, I find the browser a really good start. Unfortunately with decent problems.
as already mentioned here, the built-in filters for almost all German sites do not work at all. E.g. NTV News etc.
also as already mentioned, the tools of Firefox do not work, or are not loaded apparently.
the Chrome tools e.g. UBlock is displayed and seems to work, but the ublock settings are not there, or just have a white page.
once you have ublock or so installed, your own content blocker and tracking settings are barely adjustable. Everything seems to be blocked. Nothing works anymore.
The extensions can also no longer be uninstalled. The browser must then be completely uninstalled itself and reinstalled.
Cheers
