Powered by the same engine as Firefox 2 and the upcoming Thunderbird 2, SeaMonkey 1.1 includes numerous enhancements including more visible security indicators in the browser, enhanced phishing detection for e-mail, a new tagging system for e-mail, support for multi-line tooltips, image preview in tab tooltips, inline spell checking in the browser, an updated version of ChatZilla and a significantly improved startup script on Linux."

I see a "keyword" field for both Firefox and Seamonkey Bookmark properties ....
As far as I know there was some work to implement tags for Firefox bookmarks and change the backend to SQLite, which would have been good to have in 2.0. Not sure what the status is now.
For bookmark updates, there is FF extension, AFAIK.
