I use a local file as a homepage and Firefox doesn't usually allow local files as new tab pages. I wrote a script to restore the old config functionality, wanted to share it (thanks for this userscript framework by the way, it's extremely useful).
This allows a user to set a preference in about:config for their new tab page (like what Firefox used to do way back in the day), which can be any URL they choose, including local file:// URLs.
