Comment on attachment 497835 [details] [diff] [review] patch Are we sure this is ready? All other patches we care about have landed?
I don't know of any major problems preventing this. It would be nice to get bug 604101 in first, but I don't think it's necessary.

This has been disabled for all mobile platforms by http://hg.mozilla.org/mobile-browser/rev/7827ccd4bd19
