After 19 months of development, two name changes and more than 8 million downloads of its preview release, the Firefox browser is finally turning 1.0. Firefox is scheduled to be available for free download at 1 a.m. PDT Tuesday. Our Take: Sky’s the limit. After Thunderbird (and third-party NVU & Mozilla-Calendar), I would love to see the Mozilla Project build a multi-IM application (ICQ, AIM/iChat, MSN, Y!, Jabber, etc) with the same design/usability goals as Firefox, coupled with good voice and video support (support which lacks on all third party multi-protocol IM solutions today). UPDATE: It’s out.
