Do Not Upgrade to CookieSafe 2.0
CookieSafe 2.0 (a Firefox add-on) is seriously broken, It no longer allows you to manually enable or disable cookies for a site from its popup menu. I am not the only one having the problem. Stay with CookieSafe 1.x for the moment.
If, like me, you upgraded to 2.0.x and are having problems, you can still download the old version from Blaze’s web site. Save it on your hard drive; then drag and drop it onto an open Firefox window. The restart Firefox. (For some reason File/Open did not work for me.)
There’s probably more to this than I understand yet, though, because reverting to the old version 1.1.5 does not seem to fix this. That is, on the system I didn’t upgrade it all still works and on the system I upgraded and then reverted it’s broken. I’ll let you know if I figure this out.
