No need for flash/java!
Why not block any ads that were not just a single image. No flashy code, no cute animations, just a single jpg/png.
The main reason I install an ad blocker is when I notice my machine running like a dog when I have a couple of tabs open.
I’m fine with a single image I can ignore, but as soon as things start to slow down the shutters come down.
Google could easily make this happen.
