I love the Add on, but the new Google preview function consistently shows a more accurate snapshot of what the page actually contains. Isn't this the point after all? Your preview picture is sometimes the homepage of the site and sometimes a rather old snap of the site. The size of the google preview is good or bad, depending if you have a small or large screen, so this point is relative. On a 10" screen the google preview is readable. On a 17" monitor the SearchPreview preview is adequate.
I've been using this add-on for a number of years and find it a really useful "must have". Over the years the number of supported Search Engines has increased and it now supports DuckDuckGo. Can support for Startpage.com's search engine be added please.
