Interestingly enough, trying to open this link from Thunderbird 38.2.0's feed reader does nothing and opening it in Opera 32.0.1948.25 crashes the browser. Hovering over the link in Opera crashes the tab, probably due to some prefetching...

Opera 15+ operates identically to Chrome because it is just a fork with minimal amounts of changes.
