Comcast is hoping to issue a fix next week for a buggy piece of software that changes some Xfinity Internet customers' homepages to Comcast.net -- and doesn't let them switch it.
The glitch affects only customers who have used Comcast's self-install kits with Mozilla's Firefox browser on a Mac within the last two weeks. The number of affected users is very small, according to Comcast senior director of corporate communications Charlie Douglas.
"Of course anybody should be able to change their homepage to whatever they wanted," Douglas said. "We're certainly apologizing [to affected customers], and we're fixing it."
The issue was reported Thursday by computer-security blogger Brian Krebs.
The MSO identified the issue about a week ago, after the latest revision of the software was released. The problem does not affect the Windows version of the kits, nor does it affect the Mac version that works with Apple's Safari browser.
The Xfinity Internet self-install leads users through the process of setting up service. The software changes the default browser's homepage to Comcast.net on setup, but it is supposed to allow users to change that.
Krebs provided a link to another blogger, who provides instructions for Mac users on manually resetting the Firefox homepage.
Comcast is the largest Internet service provider in the U.S., with 17.4 million broadband subscribers as of the end of March 2011.
