Internal browser manual posting with Scrapebox

If I post with the internal browser set on manual mode with Scrapebox will it switch IP addresses for each post or for each website or ?

I have several sites that I would like to promote by commenting on these sites. Can I just make a comment for all the sites one after another or do I need to go through the list and comment for the first site then go through it again to comment for the next site.

*bump

wondering this as well

Scrapebox's internal browser has a dropdown to choose proxy from your proxy list. Recommend: reload page or switch before visiting page before commenting (so comment reflects proxy'ed address)

Hadnt thought of using this feature, but think I will give it a try. Beats manually changing the proxy ip in my firefox browser everytime.
