I installed adblock plus the same way the thread starter did, and unfortunately it has a negative affect on the browsing experience...

it seems, that I do see some kind of checkerboard pattern much more and much longer than before, and furthermore, there are issues with the switch to the fullscreen (or back from fullscreen), sometimes i get a black screen and have to tap again, and then it still needs some time to get everything running smooth again

I now uninstalled adblock plus and, altthough ads are shown, the browser seems to be faster and more direct...

not good news, I hope that there will be new version of adblock soon, without such a significant performance hit (installing adblock plus 1.1.1, shown in a link few pages before did not work, ads were still shown)
