It&#x27;s entirely inconsistent with Mozilla&#x27;s past actions.<p>You can compile Firefox source code of which 100% of it came from released Firefox versions in Mozilla&#x27;s HG tree and they won&#x27;t let you call that &quot;Firefox&quot;. Part of why IceWeasel exists is Debian wanted to backport security patches from  Firefox releases into an older version (eg. apply security patches from Firefox 4 to Firefox 3.5) for Debian-stable and Mozilla wouldn&#x27;t let them use the name Firefox if they did that.<p>Therefore your claim that<p>&gt;  Firefox is the UI chrome and corresponding stack<p>doesn&#x27;t match the reality of what Mozilla has done. It seems now Firefox is anything that Mozilla calls Firefox.
