Those three buttons actually are not normal bookmarks. They are "bookmarklets", or scripts that operate on the current page. If you try them on a page with the kinds of content they look for, then you should get an overlay letting you do things with that content. However, they may be blocked from running on some Firefox pages (such as the built-in home page or the new tab page with the nine thumbnails).

Also, some bookmarklets are not designed to work with the "mixed content blocker" introduced in Firefox 23. If you noticed a "shield" icon appearing in the address bar (to the left of the current site's URL) then that is the problem. This article has more information on the mixed content blocking feature: Mixed content blocking in Firefox Unfortunately, the unblocking method described in the article only refers to scripts present in the page when it is loaded. Since the bookmarklet doesn't run until after page load, there's currently no convenient way to unblock it.

Problems with bookmarks and history not working properly can be caused by a corrupted places.sqlite database file.

You can check for problems with the places.sqlite database file in the Firefox profile folder.

The three bookmarklets work properly, but the actual bookmarks on the toolbar do not. I'm sorry I wasn't more clear on that.
