It doesn’t work on Firefox 3 RC1, instead set “browser.places.smartBookmarksVersion” to 0 and restart Firefox.

Thanks, updated the post accordingly.

Thing is, if you just star it it doesn’t appear anywhere – you have to go into the Organiser and then Unfiled Bookmarks to get at it, or remember either part of the address or the name.

You can place the “unfiled bookmarks” folder anywhere you would like and it will still work. If you want it on the Bookmarks Toolbar you can do that. Then it’s just as easy to access.

With Safari on the PC being damned fast and Opera having everything but the kitchen sink whilst still being speedy the only thing thats holding Mozilla above the rest is extensions and existing market share. If they don’t come out with something new (Microsoft have two new ideas for IE8) or reduce their memory consumption (by default the browser does less than Opera and takes more memory) then they’ll fall behind.

You can actually create different ones yourself. To make a new one just search for something in the Library and save the search. Then open its parent folder and select the search you saved. You’ll see in the info pane a place: uri. You can change this uri and add new criteria like limit the results to a certain date.

We are actually working on an article along those lines. We’ll explain what some of the different parameters do and how you can really customize them. Thanks for the resources to look at!

Of course they’ll be upgrading it, and I would assume that they would do so before the final version of the browser is released. I honestly believe that’s one of the reasons development has gone slow… to give the “big” extensions time to get a Firefox 3 compatible version released.
