I use CCleaner after I exit Firefox. After Firefox's update to 81.0.1 (64 bit), I began to see 7 "trackers" identified every time I exited Firefox and ran CCleaner. I've never seen this before. Unfortunately, CCleaner does not identify who or what the trackers are, but they are now consistently found. Has this happened as a result of the latest Firefox update? Many Thanks for any info offered.
