So, Mozilla appears to have just released Firefox Quantum; they claim to have rebuilt the browser from the ground up, with speed improvements in-mind. And, well, I have to say the following: I have tried it out within Sierra, on a modern Mac, and I can conclude that Mozilla finally has made a browser that's actually fast and efficient. This has GOT to be great for PowerPC users, assuming that TenFourFox is updated with these technologies. It's going to make the application run better on PPC Macs than ever before. Personally, I loathe how slow and hungry Firefox/TenFourFox is; so, if this marks a turnaround, I'm relieved. It's great for any Firefox user - including PowerPC-Mac users. Can't wait for an update; I'll go test it on my PowerMac G5. P.S. New icon design + new tab design.
