So my Firefox crashes and closes down all the time. I mean, ALL THE TIME! I got a little pop up saying that it may have to do with Data Execution Prevention settings. So I checked it out and it says that DEP shuts down programs that may be using memory incorrectly to prtoect the computer from secutiry and virus threats. It says that I can choose to turn off DEP for certain programs. Is it wise to do this for Firefox or will that open up the computer to a possible virus that may slip through Norton? Or should I just try re-installing Firefox? Thanks.
