To close it, I have to right click the title bar and select "Close", and then I have to go into Task Manager processes and do an end task for all instances of firefox.exe, otherwise it takes a long time for the processes to end, and sometimes they do not end at all. After doing an end task, many times (but not always),es I get this popup error: firefox.exe application error the exception breakpoint a breakpoint has been reached 0x80000003 occurred in the application at location 0x5783ea13. Sometimes, but not always, the above error is followed by a Sandboxie error SBIE2224 Sandboxed program has crashed firefox.exe (Default) I searched for the error but cannot find anything that points to that specific location, i.e., 0x5783ea13.. I have scanned for malware using malwarebytes, superanti-spyware and Microsoft Security Essentials and the system appears clean.
