Just one week after the launch of Live.com, Microsoft has added support for Firefox to its new services-based Web site. But the upgrade is not entirely bug free; a minor flaw causes the tabs in search results to display improperly. The problem will be fixed shortly, according to developers. A commenter to the official Live.com blog questioned why Firefox wasn’t supported at launch. “I don’t understand why it wouldn’t be written standards-compliant in the first place, rather than having to go back to the code to make workarounds,” a reader named Simon wrote.
