Workaround for Issue: New window and first tab when starting firefox doesn't use my HTML

1. open about:debugging#/runtime/this-firefox
2. find extension, copy manifest url
3. Go to preferences
4. Set homepage to copied url, but replace manifest.json with new-tab.html, e.g.:
moz-extension://290bd968-ee71-1841-9fc8-b88bd1c8bf7c/new-tab.html
