A few days ago I hit the wrong button in Firefox 3.6. This button deleted all the Exceptions folder. No"are you sure?" Just down the gurgler.
I have posted on the Mozillazine forum, and one of the mods says they recall that Spybot either does, or used to have such a list that could be loaded into a browser,
The absence of these exceptions is a bit of a backward step in my opinion.
It was all the tacky ones, or spyware, why they saw fit to remove it I don't know.
If Safer Networking can live up to that name and point me in that direction, I would be eternally grateful.
