I can confirm this issue on the latest nightly:
Mozilla/5.0 (Windows NT 6.1; rv:9.0a1) Gecko/20110817 Firefox/9.0a1


Issue is reproducible ever since Firefox 3.6.16:
Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.16) Gecko/20110319 Firefox/3.6.16

I'm not sure that this is a bug or whether it is intended behavior. In about:support we choose to not necessarily show every modified config. The way it works now, there is a white list of config prefixes which we do check for changes (i.e. browser.fixup.*) but not all of browser.* in general. Ccing Gavin Sharp for opin.

Felix is right - we won't show prefs unless they're added to the whitelist, and this pref isn't on the whitelist. We can add it if it's somehow useful to help debug common issues, but otherwise there's nothing to do here.

Marking invalid, meaning this is the intended behavior, as Gavin says.  If people would find it useful, we could certainly whitelist this preference and reopen this bug to do that.
