Hi i_rina,
Very much appreciate your response.
My greyed out icons were just my long-established Favorites.
I did try Restart but they just stayed greyed out. Based upon an earlier piece of advice I also tried going to a Favorite website multiple times but nothing happened. They stayed greyed out.
Before trying your suggested start up in Safe Mode, I tried one last thing--I clicked on a Favorite (Vox) and then selected "Add a Bookmark." I thought it might duplicate that Favorite and that the duplicate might not be greyed out. Lo and behold, I got a new (replacement?) Vox Bookmark with its distinctive Yellow icon!
I then repeated the process with all 23 icons. I bit of a pain but it worked.
As you might have worked out, I am not very technical but sometimes things work out "by accident."
Anyway, problem solved, but I am sure that the other solutions you proposed would have worked a lot faster.
Thank you so much for your kind and helpful answer.
