CCleaner not deleting Chrome or Firefox websearch History?

For some reason, my CCleaner (5.06.5219 64 bit) has stopped cleaning Firefox and Chrome websearch history.

I think it did before? ... After running CCleaner with the boxes selected for Internet History, Internet Cache, and Download History, CCleaner seems to run okay and says in the results the files as deleted.

But, if I open Firefox or Chrome and look at History ... it shows a listing of all the website/searches I performed.

Am I missing something ?
