No More Firefox 'Better Privacy'

Just discovered that that add-on, that I've used for years, "...has been removed by its author."

Well hell, that's no good at all. I used that add-on for years to capture & delete flash cookies. It literally snagged & deleted thousands of flash cookies in that time.

Now it's gone, since who knows when, & my laptop is polluted with, I imagine, hundreds of flash cookies. What an unsettling thought that is!

I definitely need to find & install a Firefox alternative. Any suggestions?
