I love FIrefox browser and prefer to use it on all my devices, PC, Smart Tv, Phone, Tablet etc. In recent times Iv'e had problems though, everytime I try to comment on a facebook post with each key stroke the cursor jumps back to the beginning of the text field and by the time I finish typing I look up and find jibberish, yesterday I upgraded this RKM Mk902 Android device that I am typing on now unfortunately using Chrome from Anroid 4.2.2 to android 4.4.2 Kit-Kat and thought I would no longer have that problem but the issue is still there. I also have discovered I'm having similar problems with FireFox on my Cube U39GT tablet. As I spend more time on Facebook than any other website I have to find a solution. I thought it may of been one of the addons that i use causing the problems such as Phony but I still get the issue without the addons and after a clean install. Please help me sort out this problem so I can once more use FireFox on my Android devices.
