I'm also experiencing this bug on 4.0rc1 for Windows
Build ID  : Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0) Gecko/20100101 Firefox/4.0

from prefs.js (source of about:config):
user_pref("extensions.checkCompatibility", false);
user_pref("extensions.checkCompatibility.3.6", false);
user_pref("extensions.checkCompatibility.3.6b", false);
user_pref("extensions.checkCompatibility.3.6p", false);
user_pref("extensions.checkCompatibility.3.6pre", false);
user_pref("extensions.checkCompatibility.3.7a", false);
user_pref("extensions.checkCompatibility.4.0b", false);
user_pref("extensions.checkCompatibility.4.0p", false);
user_pref("extensions.checkCompatibility.4.0pre", false);
