Firefox 100 Brings HDR Video and Other Features to Mac

Firefox today announced the launch of Firefox 100, the newest version of the popular browser that serves as an alternative to Safari and Chrome. Firefox 100 brings new features for both mobile devices and the desktop to enhance the browsing experience.

On Macs, Firefox 100 supports High Dynamic Range (HDR) video for higher-fidelity video content. The feature requires a Mac with an HDR-compatible display that's running macOS 11 or later. Also new to the desktop, there are subtitles and captions when using Picture-in-Picture mode. Subtitles and captions are available on websites that support the WebVTT format, such as YouTube, Netflix, and Prime Video.

A new language switching feature allows Firefox to detect a device's language preference and ask whether a user would like to switch to their preferred language, and credit card autofill functionality has now expanded to the UK, France, and Germany.

As for iOS devices, the update brings clutter-free history and clutter-free tabs for better organization, plus it includes new browser wallpapers for personalization. The history feature groups history items by the original item, so you can, for example, find all the websites you visited under a specific search term. History is also now searchable.

To cut down on tab clutter, Firefox for iOS will now focus on recent tabs in the tab tray to make it easier to swap between what's current. When a tab hasn't been visited in 14 days, it is moved to an "inactive state" in the tab tray. In that situation, the tab is available, but out of the way until you need it.

The updated version of Firefox for Macs can be downloaded from the Firefox website, and the iOS version can be downloaded from the App Store. The iOS features will be available later this week.

With just three days to go until the iPhone Duo is released, Apple is getting ready for the launch. Behind the scenes, the App Store now has screenshots of Apple's built-in apps running on the Duo. We've seen some apps in marketing materials, but images of the ones we haven't seen give us an idea of what it will be like using the iPhone Duo day to day. Many apps are shown in landscape...

Apple Music Has a Hidden iPod You Can Play With

Apple Music has a 404 page easter egg on the web: a functional iPod that appears when you load a page that does not exist, such as music.apple.com/macrumors. "Page Not Found," says Apple. "Give this a spin instead." Apple is clever with this. If you navigate to music.apple.com/ipod instead, the page says "Looking for something?" instead of "Page Not Found." The easter egg is only...

Although not perfect, I switched to Firefox recently, mostly because I'd hate to see it go and everything web would go down the Chromium path.
There is a dire need for competition in browsers, for the openness of the web. You can thank me later ;)

I'm a devout Firefox user but it's not clear how much longer Mozilla can keep the project going with their market share in the single-digits and still falling. It'll be a sad day if and when they finally discontinue development.

I have been a devout FF user for as long as I can remember. You should have seen how much I fought against having to install Chrome to test an internal CRM because that was the only supported browser. It is not perfect, but it is such a great browser and, as another poster pointed out, there is no other real competition for Chromium in the browser space.
