I strongly recommend CS Lite be installed with ThunderBrowse Rated 4 out of 5 stars
I was using ThunderBrowse to log in to selected sites. Then I noticed that everytime I visted the site, I was somehow logged in.
As I was looking for a way to clear my cookies in ThunderBrowse, I couldn't find that option. So I installed CS Lite (Cookie Safe Lite).
I then saw all the nasty cookies accumulated in from ThunderBrowse. I suggest you install CS Lite in addition to ThunderBrowse.
Still, great extension
