Just discovered a link and recommendation at another site, then read a bit.
Presently have it attached.
It definitely caught my attention that I had scores of Local Shared Objects, LSO, dating back a few years in duration some from sites I remember browsing, others no clue what they are, still others annoying reminders of some spammie thing I was investigating and thought I had deleted with ATF-cleaner or CleanUP! 4.52 or Windows Disk Cleanup.... Not so.
I'll be test driving this add-on.
Are others of you already using it?
