Not surprising, as the feature hasn't worked for quite some time, despite still being available to configure within your settings. I am disappointed however, because there are quite a few sites on the Internet that I would much rather not see at all, ever again. They are the noise in my search for signal in my Google search results. And the entire point of switching to Google way back in the day was the quality of their search results versus what was available in the late 90s.

Being able to personally fine tune those results myself, outside of what a robot thought to "personally" customize my experience to, was a great feature. Suggesting I use a third party plugin for a browser I don't use is hardly a compromise or a solution, and does nothing for my Google search results on mobile platforms where that plugin is not now nor will likely ever be available.
