Tor Browser's homepage is currently hardcoded in (`aboutTor.js`). ``` kAboutTorURL = "chrome://torbutton/content/aboutTor/aboutTor.xhtml"; ``` It would be nice if there was an `TOR_HOMEPAGE` environment variable to configure this. Would be useful for (linux) distributions that want to set a divergent default. I am going to submit a git branch that adds this feature soon.
