I've posted about this before and no one seemed interested but I'll try again here. I found a very simple, and I suspect old, browser called OffByOne. It is a free download. It's very small. There are no pop ups, no adverts, no hidden scripts, it's just a simple HTML browser. It's perfect for text based forum stuff like Muscat. It wont run videos and it wont run animated ads. It's very fast. Try it.
