I've used AdBlocker for years on all kinds of browsers. It completely changes your browsing experience, finally it's back the way things were in the early days before "monetizing" everything made the web nearly unusable. I'm a huge fan of free software, but I send these people money. I just sent them £20 because they've done more for me than windows ever did. Get it, use it, send them a bit of cash: they're worth it.
