Tor Project recently received funding to factor out the security and privacy enhancements of Tor Browser from the Tor-specific enhancements (similar to how Kicksecure factors out security features from Whonix). The factored-out browser is called Base Browser . This is basically the same concept as SecBrowser, which was deprecated by Kicksecure due to insufficient support from upstream Tor Project. There aren’t yet any Nightly builds of Base Browser, but code is already being committed to Git; I’m not sure what the expected release timeline is.
It might be useful for Kicksecure to consider including Base Browser once it’s released (at least as Nightly). I’m guessing the Tor Browser Downloader in Whonix could be trivially adapted for Base Browser.
 I was initially not very fond of this name, but it’s grown on me, especially once I realized that it opens the door to entertaining memes such as “In Soviet Russia, all your tracker are belong to Base Browser.”
