Shoot!! I just filled this out, and somehow, it reverted me back to This screen again!! I am not a programmer or IT Guy. What I am is a person that is Very alert to sudden changes in my experiences. I retired 14 years ago, as a Manager in a Manufacturing industry. Very familiar using desktop. For some reason, about a couple weeks ago, some of my sites have begun using google adds, over and over. When I click on the "X", wants to know why, etc. I use Malware Bytes, scans every day. Does NOT discover any malware, but I KNOW something has changed to allow the bombardment! Is it possible it's just a single site that I had to change and log in to? Even if so, WHY doesn't Malware stop them? Should I try a system restore to weeks ago? I am on here Every day.so I'm pretty cognizant of changes! ADVICE PLEASE!! Bruce Pierce

Firefox uses about half a gig on my disk, that's: '~/.mozilla' and '~/.cache/mozilla' can that be reduced? Either some setting that limits disk use or even a manual deletion of ancient stuff?
