Little Snitch and Devonsphere

Hello,
Each time I open a webpage, Little Snitch requests permission for DEVONsphere to connect to several ip addresses --not all of them are on port 80. Are all these connections necessary. Anyone using Little Snitch have a workable rule setting to share other than carte blanche blanket access? Thank you.

You could enable usage of Thumbshots.com (see Preferences > General) to reduce the number of requests. However, there might be still one request for each viewed webpage to retrieve its source & fav icon.
