Hi havent played around with it much,initially for "move" highlight the bookmark then click the organise tab again and move appears in the drop down menu. Rename,rightclick the highlighted bookmark>properties>change name or when highlighting the bookmark it appears in the main body of the page (bottom) Bookmark menu right click? show all bookmarks>open bookmarks in main body and then view>sort(a few diff options) I guess this is why it is still beta?
Although not yet decided is it easy enough to change back again? I didn't save my bookmarks before downloading as I had assumed I could look at old version alongside the new, and not expecting it to overwrite!
Yes indeed a word of caution is needed before you mess around with Firefox 3. It downloads into a separate folder from Firefox 2 and if you just leave it like that there is no problem but if you start adding/changing add-ons or themes then those changes appear to affect your profile for both versions. I installed one of the few themes applicable to Firefox 3 and then discovered that it had changed my preferred Firefox 2 theme as well. You may have to uninstall Firefox 3 and rebuild your profile for Firefox 2 to get it back the way you want it.
