When I check the box "Do not display this message again" , Mozilla seems to accept the input (in contrast to other threads and bug reports I do NOT get any error message!) And even every mailto Link works fine (opens Mozilla Mail!). But after closing and restarting Mozilla , I do get the same question again and again. By the way, this error did NOT occur with version 1.8a5! Reproducible: Always Steps to Reproduce: 1. Close Mozilla 2. Open Mozilla Mail 3. Actual Results: Getting the popup with the question "Do you want to use Mozilla as the default mail application". Expected Results: After checking the button "Do not display this message again" , no popup should appear after restarting Mozilla Mail.
