How do I turn off the prompt to launch in safe mode?

I noticed that since Firefox 18 on Windows 8 I have observed the safe mode window here: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode?esab=a&as=aaq#w_saf... pop up when Firefox crashes asking me to launch in Safe Mode.

This window is useful, but I would like to turn it off. The circumstances under which I'm using Firefox require that it just loads into the browser window immediately (I'm doing automated browser testing. The reason my browser stopped is that I killed it with my script sending the command 'taskkill /f /im firefox.exe' or 'killall -9 firefox')

The safe mode window doesn't always load for me. I've only noticed it on Windows 8, not on any other platforms, but it does force intervention from me to proceed, which I want to avoid.

Any assistance in turning it off would be appreciated.

hello, you could try this - enter about:config into the firefox location bar (confirm the info message in case it shows up) & search for the preference named toolkit.startup.max_resumed_crashes. double-click it and change its value to something very high like 999999 (maybe setting it to 0 or -1 will also work, however i haven't tried that myself).

The -1 value for toolkit.startup.max_resumed_crashes should work to disable Safe mode.
