For some reason i think Ad Block Plus is causing Firefox to freeze and stop responding and it's also causing my OS Windows 10 stop responding. I not sure what the exact issue is or how to fix it but it's been happening for about 2 months now, I have the newest version of Windows 10, Firefox and AD Block Plus. I have reinstalled both Firefox and Ad Block Plus and i have also cleared the browsers cookies but that didn't fix the issue i am having. I'm not sure if AD block Plus has been compromised by a hacker or something but i am starting to get really irritated by this series problem. I guess I'll have to stop using Ad Block Plus until this issue is fixed.
