We have it pretty good these days, extensions like AdBlock or No Script make it possible to block any web content we don't want. Browsers are even bundling options like click-to-play plugins, meaning that annoying Flash ads no longer load by default.
But these features still require some technical skill and are error prone. The more savvy users will realize why some elements aren't loading and why a page isn't working, but most regular users won't.
What's more, all of these tools come with a pre-defined scope, block ads, or block all scripts. Page Eraser for Chrome aims
to make it easier for users to remove things they don't want from web pages while at the same time make it possible to remove anything from a page, not just ads.
Using Page Eraser
is fairly trivial, you just hit the eraser button and then select whatever it is you want gone. Ads, banners or annoying toolbars will be removed and will stay hidden in the future when you visit the same site.
