This got turned on by accident I think in 1837037 and we should remove [this](https://searchfox.org/mozilla-central/source/browser/base/content/browser.js#9860-9864) line since it hasn't been used in a while. We'll also want to remove all of the code and tests (which have caused intermittent failures) if we won't be using this in the foreseeable future.
