State of the Tor Uplift

Noted by on his .


Currently, the Tor Browser is based on Firefox Extended Support Release (ESR); it lags behind stable releases by up to and only receives the subset of security backports deemed to be a high-enough priority.

The Tor Uplift project is an initiative to upstream all the Tor Browser’s patches into Firefox. Its goal is to make re-basing the Tor browser patches easy enough for the Tor Browser to track Firefox’s stable release channel. The Tor Uplift has been in progress for , with several of the Tor Browser’s biggest modifications successfully upstreamed (first-party isolation, fingerprinting resistance, and more robust proxy support).

On , Firefox 102 ESR was released. Today, on , Firefox 91 ESR will lose support. That gave a window of about three months (the duration of three Firefox stable releases) to re-base Tor Browser patches.

The first stable release of the Tor Browser based on ESR 102 hasn’t yet shipped (it’s close; an alpha version is available). Seven years into the Tor uplift, the Tor Project isn’t able to keep up with the Firefox ESR release calendar. I don’t think the Tor Uplift will succeed at getting the Tor Browser to track Firefox’s stable channel; at best, it’s keeping the Tor Browser from falling too far behind ESR.

Hmm, but does it need to bring Tor Browser on par to be a success? It has already reduced maintenance work and brought neat features into Firefox. To me, that already made it a success many years ago...
