Comment (by jb.1234abcd):

 I set it up as follows.

 My regular (production) tor browser is in dir
 /home/jb/Downloads/tor-browser_en-US/Browser/firefox
 I unzipped debug symbols file in dir:
 /home/jb/Downloads/Debug/Browser/
 $ ls -al /home/jb/Downloads/Debug/Browser/

 I overwrote original files with unzipped debug files:
 $ cp -pr /home/jb/Downloads/Debug/Browser/* /home/jb/Downloads/tor-
 browser_en-US/Browser/

 $ coredumpctl gdb 2186
 ...
 Executable: /home/jb/Downloads/tor-browser_en-US/Browser/firefox
 ...
 Reading symbols from /home/jb/Downloads/tor-browser_en-
 US/Browser/firefox...done.
 ...
 Program terminated with signal SIGSEGV, Segmentation fault.
 ...
 (gdb)
 (gdb) br main
 (gdb) run
 Starting program: /home/jb/Downloads/tor-browser_en-US/Browser/firefox
 /bin/bash: /home/jb/Downloads/tor-browser_en-US/Browser/firefox: cannot
 execute binary file: Exec format error
 /bin/bash: /home/jb/Downloads/tor-browser_en-US/Browser/firefox: Success
 During startup program exited with code 126.
 (gdb)

 It does not seem to work ...
 Can you give me instructions how to set it up properly ?
 Then I can re-run the debugging session and capture whatever data you need
 to figure out what caused the dump.
