It does finally open, but I don't understand why my three browsers don't work like they used to.
Safari, when opening preferences and then extensions it hangs up. Firefox hangs up when playing a video attached to a news story. My Firefox and Safari are better, but not super fast like they once were. Pages don't load, screens turn white/blank, can't stream football, it's horrible. I've noticed that Chrome has been getting slower and slower over the past 6 months and now it's terrible. I've turned off my hardware accelerator, and when I checked for add-ons it only showed three, and I have no idea what they were for. I've cleared my download history, my cashe, and my browsing history, cookies, you name it. Will someone help me figure out how to fix my Chrome while using my Mac? I use OS X, version 10.9.5.
