I did a search on WSF for user recommended FF add-ons and from the list I chose a few that I thought would be beneficial and I am very very pleased with the ones I chose. One of them was BetterPrivacy which came highly recommended. I read the blurb that came with the product and it stated that some LSOs are required for certain things to happen properly. Other LSOs can be deleted. When I close FF, a BetterPrivacy popup indicates the number of LSOs that are there and asks me to delete or not ... I have gone back to look at them, but I have no idea if they are they 'must haves' or the 'spying ones'. Some are google (I left them because I recognised the name ... only reason!). There were quite a few from player.ooyala.com (7 LSOs). They are all in c:/appdata/roaming/macromedia ... 5 of them appeared when I opened FF outside BufferZone (not sure that this had anything to do with the number going from 2 to 7). The player.ooyala website gives me the impression that they have something to do with advertising via video Should I delete these player.ooyala LSOs? Are they spy LSOs?
