Thanks all. I've ended up just using the Samsung Browser with the AdBlock Plus extension. Added bonus is I discovered you can even get the Samsung Browser to sync all your Chrome bookmarks using a Chrome Desktop extension called Samsung Sync!
It's actually a really good browser too. Very fast. That and the fact it now blocks ads is spot on. I use Firefox too now so I can listen to YouTube videos while it runs in background (only Browser I've found that can do this trick).
cant get samsung browser to sync any ideas how to get it to work? it doesnt show my bookmarks or my s7 edge
