Thanks Shane,
I opened this thread intending to mention that my OS is Win.10 but found you’d already answered my previous post.
I found the file once I knew it was a file, not a folder and did as you suggest, then ran System Ninja again, deleted all the ‘Junk’ and re-opened the browser and the favicons were still there…
Well done, problem solved. I’d mark this thread as resolved if I knew how…
Poppa.
