Bookmark management in all web browsers is terrible. All of them. You would think that something as simple as searching for a bookmark would be simple and easy to do but it usually isn’t.
In Firefox 3 you can at least search your bookmarks easily if you know how to do it. Fortunately this is quite easy. All you have to do is use your address bar. Just type in a word or two and your bookmarks are auto-searched along with browser history.
Most of the time your bookmarks are listed first, and that’s good. You will know if a search result is a bookmark because there will be a gold star next to the listing.
Below is a screenshot of what this looks like.
While this may not be perfect (sometimes the search is a bit too "picky"), at least you have some ability to search bookmarks.
