Bookmarks synchronizer for FF 1.5 at Personal Babblishing

There was one extension i really missed for Firefox 1.5. The extensionupdater didnt found find (?!) an update so i started to search on google. I finally found a working extension hosted on a dyndns server, and because i dont know if it will be up the next time i need it, i thought i put the file on my space.
? bookmarksync-102-FF15.xpi
