The obvious decreasing ability of Presto Opera to function on increasing numbers of https connections will probably be the thing that finally "kills" the Presto Opera version for many of its diehard users. As the universe of exploits against https protocols continues unfolding, there will likely be further changes in the Internet transport protocols and standards, as well as schemes of encryption... and a browser that is no longer being updated simply cannot keep pace. For those using Presto for non-https sites, of course, this by itself will not be a major issue - but a browser that ceases to function for an entire class of browsing is a browser with a major handicap. I know that this whole https/TLS business has become a key factor in my own significant drop in Presto Opera usage in favor of a more modern browser.
