sometimes a this directory appear: /tmp/mozilla_user0
Modification time is updated every now and then.
I think is used to store temporary data ( user data ? ).

That doesn't happen often.
For example it happen sometimes watching youtube ( maybe some advertisement or script ?) and when a download is finished to save to disk in mega, the site.

This happen when I run Tor Browser.
It happen every now and then, frequently.
My privacy settings are at default ( low ).
If I delete that directory, sometimes it is recreated.
If I close Tor-Browser, the directory stay there.

Which conditions let the directory mozilla_user0 appear in /tmp ?
What about linux x86 (32bit), Windows and macOS versions ?
That could be privacy related or worse?

Happy to contribute
