I downloaded Sanboxie for the first time and think I need some help. But first my setup: C: for Windows XP and applications included Firefox D: for personal data- music, movie, documents...... I also have moved the Firefox (and Thunderbird) profile to my D-partition. I want to use SB for nearly all my web surfing. 1. I know I can configure SB to auto delete the content every time I close Firefox. The downside is that next time I start Firefox I will not be able to see what links I have visited. (They should have different colour) And if I have saved new bookmarks they are gone. How can I prevent this from happening? Can I configure SB to always save bookmarks and visited links? Would this be safe? 2. I know some of you have configured SB to protect/lock D-partition. How did you do that? I could not find it, but as far as I can remember you had to type something, but where? 3. I may switch AV soon. My new AV could be Avira free. It does not have web guard/http scanning. Should I worry about this if Firefox is run sanboxed?
