I am also still using it and haven't run into any issues so far. But it is unmaintained for quite some time now last I checked so I assume that eventually it will just stop working.

It's quite nice though. I have it set to disable any and all third party resources by default and from there it's generally fairly easy to permit the necessary things the first time I visit a site. And if it proves to be difficult I generally just decline to use that website at all.
