I wouldn't trust Chrome's extra methods in this case. Nothing against Google whatsoever, but closed source, commercial software from a company the NSA has expressed a great deal of interest in fooling around with is probably the worst possible choice in this case. Same with Safari and IE.
Google and other corporations still represent a huge risk in that they can be compelled to degrade or modify the feature, and since all you get is a binary blob, you have no way of knowing.
The security provided by the feature, in this case, is then questionable. I'd trust Firefox and Chromium, but not Chrome for this reason.
