[tor-commits] [tor-browser/tor-browser-38.6.0esr-6.0-1] fixup! Bug 16620: Clear window.name when no referrer sent
commit bc8af4dcdafd3de656bbff245eb70a0025829b90
Author: Kathy Brade <brade@xxxxxxxxxxxxxxxxx>
Date: Fri Jan 29 16:47:26 2016 -0500
fixup! Bug 16620: Clear window.name when no referrer sent
Only clear window.name for the top document, not for frames. This fixes
Bug 18168: iframe-based AJAX call opening in new tab
and more closely matches the behavior of Torbutton's old
JavaScript-based implementation.
