I'm not expert on CSS selectors, but is there a way and would it work to select
only for links that contain e.g. "aw-search-results" in their class? It sounds
that things like "a-spacing-none" and "a-link-normal" are not really
distinguishing elements of the links you want to find and click on.

:( I guess there is no better way to match these items?

Also sorry for the quoting madness, I filed crbug.com/709929

[ssid, 2017/04/11 03:55:57]

There is this other way. But i thought dummy_img looks weirder than that.
