Firefox: Disable automatic safe mode after crash

Question

How to prevent firefox showing the safe mode dialog after the crash?

It blocks the automatic selenium tests.

Answer 1

I have no idea how you got this and what your testing flow is. So I can't reproduce and test the solution. But Firefox Safe Mode can be disabled by setting the key toolkit.startup.max_resumed_crashes in about:config to -1.

Here's how to start Firefox with that preference set in C# binding:

FirefoxProfile profile = new FirefoxProfile();
profile.SetPreference("toolkit.startup.max_resumed_crashes", "-1");

IWebDriver driver = new FirefoxDriver(profile);
