User Agent: Mozilla/5.0 (Windows NT 5.1; rv:33.0) Gecko/20100101 Firefox/33.0 Build ID: 20141113143407 Steps to reproduce: First, it is an upgrade with this kind of command line: "%~dp0Firefox_Setup_39.0.0_(FR).exe" -ms -cleanupOnUpgrade Then, to keep firefox default browser, another command line: "%ProgramFiles(x86)%\Mozilla Firefox\firefox.exe" -silent -setDefaultBrowser Actual results: On the second command line, if no profile exists in AppData, Firefox creates the profile and crashes. C:\Users\CURRENTUSER\AppData\Local C:\Users\CURRENTUSER\AppData\Roaming Launch without -silent switch doesnt crash (the switch produces the crash) Expected results: No crash This can be tested easily by removing the 2 folders and starting with -silent switch: C:\Users\CURRENTUSER\AppData\Local\Mozilla C:\Users\CURRENTUSER\AppData\Roaming\Mozilla The version tested is 39, but could be valid with actual version as well
¡Hola! I do not see "-cleanupOnUpgrade" documented at https://wiki.mozilla.org/Installer:Command_Line_Arguments Could you please provide samples from about:crashes when this crash occurs? Please see https://support.mozilla.org/en-US/kb/firefox-crashes-troubleshoot-prevent-and-get-help#w_get-help-fixing-this-crash ¡Gracias!
