Kurtz'sKompund writes "Mozilla has announced that Firefox 3.0 has passed a major milestone! The Places feature has been added to the alpha client slated for release next week. Places is a complete re-work of the bookmarking and history browser functions. It was at one point slated for Firefox 2.0, but will instead see release in Mozilla's next major version. '"We enabled the Places implementation of bookmarks on the trunk," said the Places team in a post to the Mozilla developer center blog. "Although there is still much to be done, this is an important milestone for us." Firefox 3.0 alpha 5 is scheduled to launch June 1. Because Places uses the open-source SQLite database engine to store and retrieve bookmarks and history entries, it's incompatible with earlier Firefox editions' bookmarks. Alpha users must convert their existing entries, Mozilla developers said."
