My Firefox stored password have disappeared

I’ve been using CSC for over a year without any problem. I configured and run it every Saturday. However since last Saturday cleaning I discovered that,

  1. My Firefox stored user-names and passwords have disappeared, forcing me to provide and store them again. It didn’t happen before and I don’t want it to happen any more.

  2. My Chrome icons in bookmarks toolbar have lost their logos, forcing me to click on each one in order to bring to life the logos again. It didn’t happen before and I don’t want it to happen any more.

I suppose I can achieve that by checking/unchecking some option(s) in the the Firefox and Chrome privacy cleaner configuration, but I don´t know which option(s) would be.

I’ll appreciate any guidance about.
