Is there a possibility of preventing to run Mozilla Firefox in the safe mode?

I am using some plugins that ban acess to certain sites but my lil brother is smart enought to run mozilla in a safe mode and get on them.

How would you solve this problem if it was your lil brother ?

  • Do you require a password for logging on to your computer? If so, it is possible to control specific apps for specific users. – RCF Jun 14 '15 at 22:39
  • It may be more robust to do filtering at the router level rather than in the browser. – thomasrutter Jun 15 '15 at 01:29

You could try this

  • Enter about:config into the Firefox location bar
  • Search for the preference named toolkit.startup.max_resumed_crashes.
  • Double-click it and change its value '-1'.

If you check this you can take a look on:

 // check whether safe mode is necessary
855   int32_t maxResumedCrashes = -1;
856   rv = Preferences::GetInt(kPrefMaxResumedCrashes, &maxResumedCrashes);
857   NS_ENSURE_SUCCESS(rv, NS_OK);
858 
859   int32_t recentCrashes = 0;
860   Preferences::GetInt(kPrefRecentCrashes, &recentCrashes);
861   mIsSafeModeNecessary = (recentCrashes > maxResumedCrashes && maxResumedCrashes != -1);
