That's what message ignoring and domain blocking are for. The former will hide all messages of one type (identical message, source and line number) until you close the console, the latter will simply drop everything from one domain/extension forever¹.
In your examples, just block the domains <kbd>foxytunes</kbd> and <kbd>google-toolbar</kbd> and you should be fine.

¹ Known draw-back: domain blocking currently doesn't work with all Toolkit applications due to the "@mozilla.org/permissionmanager;1" component not being shipped everywhere. --
Phil: to work around this limitation, you could serialize <code>gBlacklist.mBlocking</code> into a pref and modify <code>domainlist.js</code> to use that pref instead of the permission manager...
