Comment (by cypherpunks):

 Digging a little more into this, it's not clear whether
 "clipboard.autocopy" actually does anything.

 http://kb.mozillazine.org/Clipboard.autocopy states:
 > In Linux and some UNIX-like platforms, selecting text will automatically
 copy the contents of the selection to the clipboard. Mozilla also follows
 this convention on these platforms. This preference controls that
 behavior.

 Whoever wrote this doesn't know what they're talking about (or, at best,
 is using really misleading terminology.)  On X, the standard convention is
 that selecting text automatically places it into the PRIMARY selection.
 The CLIPBOARD selection, in contrast, functions like the system clipboard
 on Windows/Mac, and is normally only set when you press Ctrl+C or similar.

 Moreover, I don't see any difference in behavior here:
 * in Tor Browser with clipboard.autocopy set to true, selecting text sets
 the PRIMARY selection and doesn't affect the CLIPBOARD;
 * in Tor Browser with clipboard.autocopy set to false, selecting text sets
 the PRIMARY selection and doesn't affect the CLIPBOARD.
