These add-ons are currently part of IceCat: * HTML5 Video Everywhere! * HTTPS-Everywhere * GNU LibreJS * IceCatHome * Private Browsing Tor Proxy * SpyBlock
A problem is that you are restricted to keep them, the "Uninstall this add-on" feature does not exist for them in Add-ons Manager. Can you please enable "Uninstall this add-on" feature for all add-ons.
