Without the patch in bug 728749, opening links in browser-agnostic UI (for example "check if your plugins are up to date" in about:addons) is really slow.
We should understand why and possibly fix the issue.
Is it quicker in a new profile? Safe mode?

Do you have a profiling setup available to see what's taking so long?
The docs say it all really, nsIURILoader starts loading the URI and waits until it sees the content type of the response before doing anything (handing off to an external app, opening a new browser window, etc.). http://mxr.mozilla.org/mozilla-central/source/uriloader/base/nsIURILoader.idl#50

This means that when you click a button that calls nsIURILoader you have to wait a full http(s) request and start of response before you see any resultant UI.
