Comment (by mcs):

 Kathy and I spent a little time today on this issue. Two `Temp-GUID`
 directories are created and used by the browser's sandbox, and this issue
 exists on all platforms. See:
 https://gitweb.torproject.org/tor-
 browser.git/tree/toolkit/xre/nsXREDirProvider.cpp?h=tor-
 browser-68.6.0esr-9.5-1-build2#n706

 The base directory comes from https://gitweb.torproject.org/tor-
 browser.git/tree/toolkit/xre/nsXREDirProvider.cpp?h=tor-
 browser-68.6.0esr-9.5-1-build2#n616; on Windows it is
 `NS_WIN_LOW_INTEGRITY_TEMP_BASE` (aka `"LowTmpDBase"`) and on Linux and
 macOS it is `NS_OS_TEMP_DIR` (aka `"TmpD"`).

 It is tempting to change the implementation in
 `xpcom/io/nsDirectoryService.cpp` that handles those two locations to
 return a base directory that is within the Tor Browser data directory.
 Kathy and I are not familiar enough with the sandboxing code and other
 uses of those directories to know what might break if we made such a
 change, but we could try it in and see. Proposed locations:
  macOS: `TorBrowser-Data/Browser/tmp/`
  Windows and Linux: `Browser/TorBrowser/Data/Browser/tmp/`
 Another potential problem is that if the browser leaves any files behind
 in this new tmp directory they will not be cleaned up (unlike the OS temp
 directories, which will get cleaned up eventually). I suppose we could
 delete the contents of the tmp directory early in browser startup.

Comment (by AxelF):

 I'm pretty sure it is created by Firefox, because more of such directories
 are being created when I start the regular Firefox.

Comment:

 Not sure what is causing this behavior, but ideally there should be no
 (empty) directory created in /tmp I think.

 I'm using the latest TBB on Linux.

 After I start TorBrowser, the directory is created in temporary direcrory
 (in my case /tmp)

 drwx-- 2 user user4096 Mar  1 12:34 Temp-
 41d8a42b-5545-4af5-89c2-be2502af95c7

 The directory is empty. After I close the TBB, this directory disappears.
 Not sure if it's OK behavior or not.
