Yahoo! launched its Axis search browser for iOS, PCs, and Macs this morning, but did it rush it out the door? Some have found it strange how Yahoo! offers Axis as an extension rather than an actual browser, and that may have lead to a security issue with Chrome. Extensions are signed with a security certificate so that Google knows it comes from a trusted source. Yahoo! seem to have included its own private certificate in the browser code for all to see.
