Yes, I regret it as well, but even getting Classilla to TLS 1.1 would be a big deal, and 1.2 (let alone 1.3) would require a lot of rewriting. $DAYJOB is crazy at the moment, and keeping TenFourFox up with Mozilla's monthly release cadence is taking time away from me doing more Power ISA work on mainline Firefox for the Talos II I'm typing this on (let alone other fun projects I'd like to get to). Classilla just loses out because of the amount of work needed to fix it and the very small amount of cycles I have available.
