Was a great add-on for gaining real estate, but stopped working. Rated 4 out of 5 stars

As the title says, it was great for reclaiming some screen real-estate. But due to an unrelated issue where I had to reinstall my profile, it no longer wants to work on the latest Pale Moon variant of Firefox.
Hope this gets resolved soon.

This review is for a previous version of the add-on (1.2.1-signed.1-signed).
