I'm glad your problem is solved.
Regarding the browser: There's no need to use the snapshot. The stable version runs perfectly and is updated promptly via cherry-picking.
Vivaldi also has a great integrated ad and tracker blocker.
I wouldn't experiment or install anything at the OS level.
If anything, configure a filtering (but not logging) DNS server at the router's perimeter edge.
For example...
