We've looked at Google's new Instant Preview feature (and showed you how to access it with the keyboard), but if you don't like the previews popping up all the time, you can ensure they stay hidden with these AdBlock filters.
Google's Instant Previews are cool in theory, but I found that their constant popping up just gets in the way of me reading my search results. Thankfully, reader kettlewhistle tipped us off on how to disable it. Just open up your favourite AdBlocker's preferences, and add the following filters:
google.com##.vspi google.com##.vspib google.com###vspb
Voilà! After applying these filters, the magnifying glass, blue box and preview window should go away completely. As several commenters point out, you need to copy the same filters for google.com.au as well to ensure full coverage.
