I've seen this program has had this problem before, and it seems to be occurring to me now. I try to load a webpage, and it will sit, and in the bottom left, it says waiting for extension adblock plus. I looked at the task manager, and it seems to be eating 25% of my cpu while adblock is turned on. Meanwhile Firefox while running adblock does not do so. Unless an update occurred some time within the last couple of days, nothing has changed from when it WAS working fine and now.
I have adblock installed on a Firefox browser, where it reads version 2.6.9, while Chrome's is 1.8.12.
My Chrome is version 43.0.2357.81, I'm running Windows 7
