OK, thanks, I’ve now added (and run) CheckPlaces, and while it didn’t seem to have any luck finding missing favicons, it did find that a couple of bookmarks I haven’t used in ages are now dead links.
(Edit, forgot to include in this posting) I’m not clear what their definition of “Questionable” links is, of which it found quite a few. It seems to somehow relate to redirects, so possibly my bookmarks just aren’t up to date for those sites. Fix-all for this tab didn’t seem to do anything, but maybe it did the corrections quite quickly so I didn’t notice … I’ll try another scan later on to see if I still get them.

It did a pretty good job of finding/getting mine it did take a fairly long time as I had 1607 bookmarks at the start. It found lots of old dead links. Yes it would be nice if they had some definitions of what the sections meant.
I tried again later and this time all the Questionable ones were gone. So I guess “Fix all” really did work quite quickly, at least on my broadband.
One setting I changed on the second run was to remove the check for duplicates. I do use the Bookmarks toolbar and find it quite handy for places I visit frequently, and leave a copy in the main bookmarks menu in case one or the other gets corrupted. And naturally, CheckPlaces insisted on “warning” me about the (deliberate) duplicates.
(Edit) Apologies to those who feel we wandered too far off the main topic with this sub-discussion. I for one am satisfied with the result and done with it.
For what it’s worth. I have kept the FF v3.5 UI.
@ DavidR The FF UI that you posted isn’t really all that ugly.
