![]() ![]() Come on in: Power ISA isn't dead, not by a long shot. Myself, with this port working, I've migrated almost entirely from QEMU to SheepShaver except for a few apps that still have compatibility issues. SheepShaver, the well-known classic Mac OS emulator (which many of you use to run Classic apps in Leopard), is now ported to OpenPOWER, so you can run it on a POWER9-based workstation like the Raptor Talos II or Blackbird. There are also Firefox add-ons that can block content. TenFourFox would regularly win benchmarks against other Power Mac browsers because its JavaScript JIT would stomp everything else, but its older Mozilla branch has weaker pixelpushing and DOM that is demonstrably slower than WebKit, and no Power Mac browser is going to approach the performance you would get on an Intel Mac with any browser. See Enhanced Tracking Protection in Firefox for desktop for details. Firefox's built-in content-blocking feature can make the pages load faster by preventing third-party trackers from loading. I use tenfourfox on my PPC Mac that has a problem, I cant listen to music because updates streaming in Adobe Flash. In case you missed it, I've always maintained that the most logical upgrade path from a PowerPC-based computer is to. Content you don't need such as ads or tracking scripts can significantly slow down page loading. I don't want to get too complex with having a "black list" for sites that need the polyfill you can add to, but maybe that's the least bad option. I'm pondering whether this is the point to add a global polyfill to the browser that could potentially cover this and other deficiencies, but although it would be nice to not play whack-a-mole so much, that would have some consequences for performance and memory use over a targetted fix like this. The workaround is needed because TenFourFox doesn't support IntersectionObserver. There are also the usual updates for the HSTS and TLD lists, and a more complete fix for non-SHA-1 OCSP stapled responses. ![]() ![]() (I said I scratch my own itches, and these annoyed me personally, so I fixed them.) If you have a custom UA for YouTube in your own settings, it should remain unaffected. The security patches mostly cover DOM and media, but the tweaks add a UA exception for YouTube to prevent it forcing you onto the really slow main page from its "unsupported browser" page, as well as a workaround for sites using lazy-loaded images with lozad.js.
