Help-> Troubleshooting information-> Profile directory

The following part is my amendments to ghacks user.js.
2- is too much, you cannot enter some websites with it. Or be ready to change it in user.js ( and in pref.js as it preserve previous user's choice) every time.
the commented option from original file was 0 (The originated server sets the cookie lifetime. (default))
it was false on ghacks-user.js, but true was the good default option
I also uncommented related safebrowsing options, for example:
user_pref("browser.safebrowsing.malware.enabled", false); user_pref("browser.safebrowsing.phishing.enabled", false);
I like some old add-ons , so
For those, who prefer searching from the address string

user_pref("browser.search.defaultenginename.US","DuckDuckGo"); user_pref("browser.search.defaultenginename", "DuckDuckGo");
