Browser Add-ons: Firefox

Recently, one of those know-it-all sites said that we didn't need 'Better Privacy' any longer, because most of its features were now built into the Firefox program. Not entirely. I just installed this into Firefox in Windows 10, and it immediately showed me dozens of these hidden LSOs ("supercookies") on my system. And it promptly removed them for me. I suggest you continue using it.

"What are 'supercookies'?" you ask. Supercookies are similar to regular cookies except they aren't detected by regular cookie-handling programs, and they are much larger than ordinary cookies, and they never expire, and they can perform executive functions just like ordinary programs do. So you want to know about them, and you want to control which of them are active on your system. Some of them do useful and necessary tasks related to websites you regularly visit, but others are just invading your privacy and snooping for personal information you may not wish to share. So I suggest you get this add-on and use it. You can choose which ones are kept and which ones removed from your system, or you can remove them all every time the browser is closed if you wish.

This is what the Options Manager looks like in Better Privacy. It shows you things you never knew you had until now.

This is something else you shouldn't go surfing without. It shows a red, yellow or green icon in the toolbar to indicate safe or unsafe sites.
