Hi Landry, dlg, and ports,

Since last "sysupgrade -s", I experience occasional Firefox crashes,
most likely related to recent pledge_socket changes[0]. I can reproduce
those crashes on any Stack Overflow thread, which I realized while
trying to understand what was going on. Of course, some configuration or
plugins of mine might interfere.
