Does Mozzilla know that Norton constant guard causes FF scrolling & video & typing to lag?


I am telling whoever reads this? That constant guard when installed & your using FF it causes a lag in typing, scrolling and video. I have and always have had Norton, but when I install CG I get that lagging problem. I delete the constant Guard and the lagging is gone. PLEASE PASS THIS ALONG Thank you.

Is it Xfinity Constant Guard? Does this run outside of Firefox or is it a Firefox add-on?

Are you running both Norton and Xfinity Constant Guard?

Yeah, I know Norton makes Constant Guard, but what you said sounds to me like you might have both installed.

Helpful Reply

yes I did, now only Norton security suite from xfinity I did not know I could not had done it before & CG crashed FF all the time. I thought they had fixed it. no crashes... but the lag. I realized the lagging started when I reinstalled CG on Monday.
