You might be right -- WP8 introduces an unmanaged C++ SDK, and some people from the Chromium project are currently evaluating it: http://code.google.com/p/chromium/issues/detail?id=153802 http://code.google.com/p/chromium/issues/detail?id=153802 The other stumbling block was a licensing issue where the Windows Phone Marketplace prohibits copyleft licenses, which prevents software like Firefox from being published there: http://arstechnica.com/information-technology/2011/02/windows-phone-marketplace-bans-the-gpl-and-the-app-store-should-too/ http://arstechnica.com/information-technology/2011/02/window... That's again from the WP7 days, so the agreement might have changed since then, but if it hasn't, and if there's no way to sideload apps onto WP8, then it's a major blocker for Firefox. Opera's last statement on the matter was on Oct 1, and at that time they were still waiting to see what avenues the SDK would allow.
