Anyway I look at it, what Bleachbit does in my Linux-Distro, it comes close to be an illusion. Looking closely what in cleans up, I have to double my efforts to wipe out some files, that

1st-> there is no need for them at all
2nd-> they pile up to a huge amount of thumbnails.png, these very tiny files with a long alphanumerical name, the size of 12 bytes
3rd-> in both cases, at first, I had installed chromium, that keeps all the stuff to remember as well.
4th-> I am doing all this to keep a little bit under the radar, not to be exposed in all detail.

So this draft above, may radical or not, is simply intended to a installation only containing Firefox on your system. At a first glance you might think, well I use FF, but while you installed (at least BSD 10.2 ongoing) the internet role, there is chromium doing a backup job in the dark. So having it simple, only Firefox, the draft mentioned above comes close to the point. So it may looks a bit radical, but it comes closer to the KISS rule, not to make too complex. I see this as well on an USB-stick, going from one BSD to Linux, there is always a second hidden /.Trash file. In both cases I am obliged to trash the trash, that is hidden. Well played, really. For me this seems to be a kind of surveillance, thats my humble opinion.

5th-> looking it up in a linux distro with systemd and finding something like this, I certainly do not need, nor do developers.

Code:

systemd-private-94730452b0264066b98697d490ce5998-rtkit-daemon.service-EHoeHd

. That can be found in the users

Code:

/var/tmp

containing nothing at all! So whats the matter with that golden rule of Keep it simple s.....????
I put loads of the /var/tmp files into the bin, they don't make sense at all. And doing so, this very procedure does not hamper at all, the Firefox or the stability of my distro.

This link posted here, it could matter to anyone, who may does not care at all. But to cut a long story short, my aim was to clean up the loads of tiny thumbnails, that amount to huge numbers after a certain time, including to club my own bookmarks.
The link mentioned above is more interesting for any who exchanges, sends or recieves images. It is about including some java source code in the alpha channel of that very image to be executed while watching some cute dogs or any other.
