This forum might not be the exact right place for this question, but Opensuse is my tribe, so here goes.
I’m using Opensuse V13.2, Mozilla Firefox, Ghostery, everything updated.
When I’m browsing the internets and go to new websites, every once in a while Firefox pauses for about 2-3 minutes, and in the lower left corner of the window, transfering data from s.uicdn.com appears.
I googled it and found several pages about it on “malicious webpage investigation” type sites, which all say it’s harmless.
How do I figure out what is going on with s.uicdn.com?
This is a noticable change, it wasn’t there in the past.
Is Wireshark an option to observe what is being transferred?

Wireshark is always an option, unless you’re using https and don’t have
access to the private key for the certificate. Even then, it can be
useful in diagnosing network issues.
What it won’t tell you is if the server has hung up on something. It can
only tell you about what’s actually on the wire.
it’s most likely a content delivery network (the cdn part of it’s name)
other sites you visit store images, video’s etc over there and that’s why you’re seeing loading s.uicdn.com
With latest FF, it’s now like Chrome and other browsers, you can open “Developer Tools” in the browser to trace traffic without a plugin.
If it is a content delivery network source, it should still be monitored warily. Anything can be deployed this way (typically common scripts, framework code, multi-media). In theory, if content is delivered this way, it will remain cached and re-usable without re-downloading when another site requires the same objects.
Sounds like the problem’s at the other end, not a lot you can do about
that unless you know the owners of the sites in question so they can look
at their logs.
