Mozilla adds -webkit prefix emulation to select sites in Firefox

 

 

The emulation is hardcoded into Firefox 39 which means that it will only work on a list of sites that Mozilla added to it specifically.

Thanks Webkit. /s

Funny thing is, when Microsoft first floated the idea of other engines parsing -webkit- CSS gunk, Apple was against it, worried they'd then have to support quirks in how other browsers parsed it.

Luckily for Apple, Microsoft and Mozilla actually care abut keeping their engines up to date and fixing bugs, so any parsing quirks will remain with WebKit.

You can disable DRM support in the normal version, this build is special in that it's disabled at compile time, and the resulting support code isn't in the binary, so these builds can't even have it enabled at a later date without re-installing a normal version.

Edit: Quite a niche market though, due to how Mozilla has enabled the DRM modules to work all their code is completely open source, and can still be shipped with Linux distros (Even with DRM disabled by default). And considering how people actually liked when Google shipped their DRM support in Chrome for Linux, I doubt many people will complain.

Yeah, I know, it is stated in the article that it is an option as well. These builds are programmed not to retrieve Adobe DRM player at all.

It requires the content provider to support the DRM first, and even then I think the client side support is still limited to YouTube playback.

Clues for the clueless: Why would Firefox be putting DRM support in it's browser? Who would want it?

Apparently everybody, Microsoft and Google pushed for the W3C to accept it, and Apple implemented support for it in Yosemite. And since Netflix required it, people were upset that Chrome didn't support it under Linux, something which has "recently" (last year) been fixed.

It's not something they wanted to do, but since users/sites/competitors wanted it there wasn't much they could do to stop it. At least they heavily sandbox the plugin from the system to prevent it doing anything odd.

Edit: And DRM support is limited to MSE video playback, something which is still limited to YouTube only because of some pretty big limitations in the support Firefox provides (exactly enough for YouTube to work and that's it).

    • Does anyone here know if these updates are integrated into the UUP dump isos?
    • Motrix Next 3.9.4 by Razvan Serea Motrix Next is a modern, open-source cross-platform download manager built as the official next-generation successor to the original Motrix project. It has been completely rewritten using Tauri 2, Vue 3, TypeScript, and Rust, while still relying on the powerful Aria2 download engine for high-speed multi-protocol transfers. The app supports HTTP, HTTPS, FTP, BitTorrent, ED2K and magnet links, offering advanced features like multi-connection acceleration, task scheduling, bandwidth control, and batch download management. With a significantly reduced install size (around 20MB), it focuses on being lightweight, fast, and resource-efficient compared to traditional Electron-based download tools. Designed for Windows, macOS, and Linux, Motrix Next delivers a clean, modern UI inspired by Material Design 3 principles, with smooth animations and a minimal workflow. It improves usability through better download organization, system tray integration, and enhanced torrent handling including selective file downloads and tracker management. Motrix Next features: Multi-protocol downloads — HTTP, FTP, BitTorrent, Magnet, .torrent, ED2K, and Metalink tasks BitTorrent — Selective file download, DHT, peer exchange, encryption controls, metadata caching, GeoIP peer flags, and tracker probing Browser extension integration — Embedded Extension API with independent authentication, download confirmation, smart auto-submit, filename hints, referer/cookie forwarding, and real-time controls (Chrome Web Store · Edge Add-ons) Safe filename handling — Content-Disposition, RFC 2047, non-UTF-8, percent-encoded, and extensionless URL resolution with path traversal sanitization Download organization — Favorite and recent folders, optional file-type categorization, stale-record cleanup, and completed history backed by SQLite Concurrent downloads — Independent controls for active tasks, HTTP connections per server, segments per file, and BT peer limits Speed control — Global and per-task upload/download limits with day-of-week and time-of-day scheduling System integration — Tray operation, optional tray speed display, macOS Dock badge/progress, protocol handlers for magnet://, thunder://, and motrixnext:// Lightweight mode — Destroys the WebView on minimize-to-tray while Rust keeps the engine, task monitor, notifications, history, and extension routing alive Notifications and power options — Native task start/complete/failure notifications, keep-awake during downloads, and optional shutdown after completion Network controls — Scoped proxy support for downloads, app updates, and tracker updates, plus system proxy detection Auto-update channels — Stable, Beta, and Latest Across Channels policies with separate download and install phases Diagnostics — Structured logs, exportable diagnostic ZIPs, database integrity checks, automatic DB rebuild, and Linux GPU rendering fallback Personalization — Light/dark/system theme, 10 color schemes, 26 languages, and first-launch system language detection Motrix Next 3.9.4 changelog: Motrix Next 3.9.4 promotes the 3.9.4 beta cycle to stable. This release refreshes bundled engine binaries, improves task detail readability and copy actions, expands link handling for magnet and ED2K workflows, polishes responsive navigation and text wrapping, updates browser extension documentation, and refines network preference controls. New Features Task Detail copy actions — Added copyable values for task metadata and reusable render functions for long text fields. Magnet and ED2K lifecycle support — Added task lifecycle handling for magnet and ED2K links. History cleanup for deleted tasks — Deleted tasks can now remove matching history records. User-Agent management — Added user-agent management and improved related network preference controls. Browser extension documentation — Added the Firefox Add-ons link for the Motrix Next extension. Improvements Engine binaries — Updated bundled binaries for supported architectures. Task Detail readability — Long task names, URLs, tracker values, and copyable metadata now render more clearly.

    • NVIDIA officially supports Ubuntu, as linked above with the GeForce NOW Hands on I did in collaboration with Paul Hill.
    • TO be clear I am not running linux today, however I keep thinking about it. And I want to make sure there are minimal obstacles if I decide to make that switch in the coming months.
    • Yes, I actually glossed over the Linux part from the OP. You could always go for a 9070 XT and if you really want to play Ray Traced games in the future, GeForce Now is pretty damn good on Linux https://www.neowin.net/news/nvidias-native-geforce-now-app-for-linux-bridges-the-gaming-gap-hands-on/
