When I regularly clean out cookies, there is one that keeps showing up in spite of my trying to remove it. Info in that dialogue box says it has been with me for more than a week. Of course, I keep all regular Mozilla cookies, but this one is strange. It is 'about.ef2a7dd5-93bc-417f-a698-14c3116864f.' Can you tell me what this is?
