Always 2 recurring problems with the latest version (5.58.7209 x64 under Win 8.1 x64) :
1. the icon of the trash remains full.
If a new passage is made immediately, it is finally emptied.
Note that I do not have this problem with Bleachbit or Privacy Eraser !
2. the Firefox / Waterfox history is not deleted.
Bleachbit encounter the same problem by reporting an error on the file "places.sqlite".
Privacy Eraser, on the other hand, erases all the history without problem.
