I've never used a browser other than IE and I won't. If something started to happen, it was always when I tried to clean the computer according to the guaranteed advice, God forbid, by some guaranteed program. My neighbor has an ajťák and when I got from him several times, I stopped using such programs, especially on the registers and there is peace. I perform updates as Microsoft precedes them. I'm new here, so I don't know how this add-on will work. If it doesn't follow the rules next time I'll get better.
