Hey Kate - is this a Pin Tabs bug?

It's more generic to CFR but could be considered pinned tabs yep

I've looked into other usages of openPreferences for Firefox Sync, Privacy Settings and they all seem to be doing the same thing (back button is active but doesn't really do anything). I don't think this is actually worth fixing.
