For some reason Google's Advance Image Search site stopped working for me, I can't open the drop-down menues, so I can't choose the size of the picture I want, or any of the other filters, so this add-on was very well received, and it works fine, but... why does it open a new tab for every search? That should be something at least configurable... it's also annoying that it dissappears if I change windows... sometimes I need to read something about the image I'm looking for, and it's very annoying that I have to re open the add-on if I switch windows, it should stay open until I click somewhere else in the browser.
