I'm at a loss, if the are no hanging Firefox/Mozilla processes in task manger and it isn't a single corrupt file. Sorry I'm not sure where to go from here.
Firefox has been on rabid release for ages,
and profiles that were valid a year ago may need to be deleted and rebuilt from scratch.
If you have already used Firefox Sync to give a fresh re-start profile that restores to a clean new profile the features you value,
you might consider testing Firefox/CCleaner with a clean and empty profile without restoring those features,
or else use the previous version of CCleaner and wait to see if the next version is better for you.

Here is my process-list from admin account, I can't see any Mozilla related things (except Firefox of course)
Can I delete my places.old-file?

or else use the previous version of CCleaner and wait to see if the next version is better for you. CAN I CREATE PLENTY OF FF-PROFILES AND THEN SWITCH BETWEEN THEM? I DON'T GET THE CLUE THAT ADMIN AND USER ACCOUNT HAVE SAME FF PROFILES, THOUGH GETS ADMIN FF PROFILE THIS ISSUE AND THIS LONG TIME AGO BEFORE COPYING USER FF PROFILE TO ADMIN FF PROFILE.
the image you provided can't help us, I need the same image taken whilst running cleaner and getting that error, please .

can you run a debug from the user account and post the log as well.
Your simplest alternatives are to provide the information as requested by Nergal,
or revert to the previous version of CCleaner and hope the next version works better for you.
BUT, if you want my response to your questions then here goes :-
I gave up on Firefox in 2011 and will refrain from giving specific detailed answers that may now be incorrect.
You will need to get information from others.
I will however state that you can create different Firefox profiles,
and select which profile to use as you launch Firefox.
I fear you may be confused by the term "profile", which means a lot more than one thing.
This is my computer "User Profile" when I login in as Administrator
C:\Users\Alan
When I launch CMD.EXE and issue the command SET it is shown as
USERPROFILE=C:\Users\Alan
When I instead login as a USER then "User Profile" is shown as
USERPROFILE=C:\Users\User
The command SET also shows (depending upon how I logged in) either
APPDATA=C:\Users\Alan\AppData\Roaming
LOCALAPPDATA=C:\Users\Alan\AppData\Local
or
APPDATA=C:\Users\User\AppData\Roaming
LOCALAPPDATA=C:\Users\Alan\AppData\Local
Please note that LOCALAPPDATA is a horrible complication due to changing from Windows XP to Windows 7.
I use Palemoon instead of Firefox.
Under XP the Firefox profile (and also the Palemoon profile) has a single path.
Under Windows 7 they each have a plurality of paths,
so when we refer to deleting a profile we actually mean deleting a plurality of paths.
It gets worse
UNDER MY ADMINISTRATOR AUTHORITY LOGIN :-
These are the two paths for Palemoon
C:\Users\Alan\AppData\Roaming\Moonchild Productions\Pale Moon\Profiles\4qbu47br.default
C:\Users\Alan\AppData\Local\Moonchild Productions\Pale Moon\Profiles\4qbu47br.default
I think that before I purged all trace of Firefox its paths were something like
C:\Users\Alan\AppData\Roaming\Mozilla\FireFox\Profiles\4qbu47br.default
C:\Users\Alan\AppData\Local\Mozilla\FireFox\Profiles\4qbu47br.default
I think there was a third path also
C:\Users\Alan\AppData\LocalLow\Mozilla\FireFox\Profiles\4qbu47br.default
UNDER NON-ADMINISTRATOR LOGIN :-
All the above excepting each path starts with "C:\Users\User" instead of "C:\Users\Alan\"
I switched from Firefox to Palemoon in 2011 because Mozilla became unstable.
One day I could view every website as intended by the website owner,
and the next day the text was in the wrong place and I could not understand the CCleaner forum topics.
Palemoon is based on the same open-source software as Firefox but without the Mozilla frenzy for something new.
I was able to install the same Addons into Palemoon that I was familiar with in Firefox,
and I because I was using LastPass and Xmarks,
when those Addons were added to Palemoon they imported from "the cloud" all my bookmarks and web-site passwords,
otherwise I could have used Firefox Synchronise to achieve the same.
If you want to try Palemoon the main page is
and a very helpful forum is
