• It could be helpful if there is a diagnostic program/add-on which control all

  installed add-ons.

• It could even be helpful If I can type/write more as 1500 characters in a

  message, because I have to tell my story (Mozilla problems) and I want to
  place the output of the 'terminal' (Sessionstore) in the same message.

• It even shall be helpful if there is a list (like in the early days of the Windows-

  browser), where I can find the description and/or the solution of the Firefox- errors. My terminal give me p.e. this output : (firefox:10353): Gtk-CRITICAL
  **: IA__gtk_clipboard_set_with_data: assertion `targets != NULL' failed; 
  Firefox: 10353 says me nothing, so..... there are errors enough, but the
  crashes don't come from the browser. I have taken all steps, my last is to
  re-install FF24 about:blank, vdpau.... e.s.o

• If I place a message here I can only put a picture-file, not a text or Gedit-file.
