How can i keep my bookmarks during the Bundle Update?

TOR browser bundle has standalone firefox broswer .

Does it come with any risk of open port that may be listening to some remote malicious service ?

You'll be safe with tor. Get the tails bundle and boot from a usb.

Yeah, get the tails version if you want super security and always boot from either the USB or live CD.

Tails bundle us great and had many other tools for privacy .
