 This user.js is mainly based on arkenfox project (56 and recent version). 
 
 
-On the other hand, it tries to avoid all the automatic connections even though security could be reduced slightly (according to Spyware Watchdog website) For instance, OSCP is a privacy breach. Nevertheless, it is also a security feature.
+On the other hand, it avoids all the automatic connections even though security could be reduced slightly (according to Spyware Watchdog website) For instance, OSCP is a privacy breach. Nevertheless, it is also a security feature.
 
 
 It has also some changes in order to improve fingerprinting like canvas.poisondata and others.
 
+Finally, it tries to resemble Firefox ESR version (useragent, buildID, platform and so on)
+
+## Known problems
+
+`Some breakage?`
+
+Try changing "network.http.referer.XOriginPolicy" from 2 to 1
