The web browsers Google Chrome and Mozilla Firefox will soon support the open video codec AV1. Google and Mozilla released support for the new codec in development versions of the browsers and plan to push the new functionality to the release channels in the near future.
Chrome 50 ends support for Windows XP, Vista, and earlier versions of Mac OS X Chrome is giving up on XP two years after Microsoft ended support for the aging operating system.
Google launched support for AV1 video decoding in Chrome 69. Chrome 69 is a beta release currently that interested users may download and run to test upcoming functionality. Chrome Beta is not the cutting edge version of Chrome; users who run Canary or Developer channel builds of Chrome have access to the new video encoder as well.
Support for the Av1 video decoded is not enabled by default in Chrome 69 at the time of writing. Google hides experimental features behind flags sometimes; users who want to give them a try need to change the status of the flag to enable or change functionality in the browser.
AV1 promises better compression rates than H.264 but encoding is significantly slower currently. The free codec has to compete with non-open codecs such as H.264 and H.265.
Chrome Av1 support
Tip: You can verify the version of Chrome that you run by loading chrome://settings/help in the browser's address bar.
Do the following to enable support for AV1 video decoding in Chrome:
- Load chrome://flags/#enable-av1-decoder in the browser's address bar. The page that opens lists all experimental flags currently available in the browser version.
- Change the status of Enable AV1 video decoding to enabled.
- Restart the web browser.
Google plans to launch AV1 support for all desktop versions of Chrome (Windows, Mac OS X, Linux, and Chrome OS) and the implementation is based on the official bitstream specification.
The company notes on its Developers site that support is limited right now as it does not include encoding capabilities at this point in time.
t this time, support is limited to 'Main' profile 0 and does not include encoding capabilities. The supported container is ISO-BMFF (MP4).
Av1 in Firefox
Mozilla added support for Av1 in Firefox 63. The version of Firefox is currently available as a Nightly release, the cutting edge channel that Mozilla maintains.
Support in Firefox Nightly is disabled by default just as it is in Chrome. Firefox users who run Firefox 63 can enable support for AV1 in the following way:
- Load about:config?filter=media.av1.enabled in the browser's address bar.
- Confirm that you are careful if the warning is displayed.
- Double-click the line media.av1.enabled.
A value of true means that AV1 support is enabled, a value of false that it is disabled. The feature may land in Firefox 63 or later versions depending on how development progresses. You can keep track of the bug here.

Advertisement One of the great benefits of Apple moving to Intel CPUs is that we have access to Google’s Chrome browser, which rapidly displaced Firefox as the alternative browser of choice among Windows users after its release in Sept. 2008. For some of us, that is coming to an end in April.
Google Chrome 5.0 (May 2010) was the first version available on Macs and Linux; previous versions were Windows-only. It never supported OS X 10.4 Tiger and initially required OS X 10.5 Leopard, which it abandoned on Sept. 15, 2012 with the release of Chrome 22. Version 39 (Nov. 2014) left behind 32-bit only Macs (Core Solo and Core Duo models from 2006), although it worked just fine on 64-bit Macs running OS X 10.6 Snow Leopard.
This time Google isn’t just leaving behind one or two versions of OS X – it’s dropping OS X 10.6 Snow Leopard, 10.7 Lion, and 10.8 Mountain Lion. Those were release in August 2009, July 2011, and July 2012, respectively, with Mountain Lion last updated in October 2013, so between them they were current for a period of more than four years and the most recent version was updated just 2-1/2 years ago.
Anyhow, here’s what Google has to say about it:
Earlier this year, we announced that Google Chrome would continue support for Windows XP through the remainder of 2015. At that time, we strongly encouraged users on older, unsupported platforms such as Windows XP to update to a supported, secure operating system. Such older platforms are missing critical security updates and have a greater potential to be infected by viruses and malware.
Today, we’re announcing the end of Chrome’s support for Windows XP, as well as Windows Vista, and Mac OS X 10.6, 10.7, and 10.8, since these platforms are no longer actively supported by Microsoft and Apple. Starting April 2016, Chrome will continue to function on these platforms but will no longer receive updates and security fixes.
If you are still on one of these unsupported platforms, we encourage you to move to a newer operating system to ensure that you continue to receive the latest Chrome versions and features.

Google hasn’t been alone at leaving behind older versions of Mac OS X. Firefox 4 didn’t support OS X 10.4 Tiger at all. That was way back in 2010. Firefox 16 works with OS X 10.5 Leopard, but version 17, released Nov. 20, 2012, does not. Firefox still supports OS X 10.6 Snow Leopard with version 44 and looks like it will continue to do so.
Update: Firefox 47 (released June 2016, last version 47.0.1 in June 2016) was the last version to support Snow Leopard, but Firefox 45esr (released March 2016, last version was 45.9.0 in April 2017) has more up-to-date security.
Let’s not even go into how quickly Apple drops support for legacy versions of OS X with its Safari browser. That’s probably one of the big reasons people using older versions of OS X are looking to Chrome and Firefox instead of Safari.
I can understand Apple doing this. They want you to buy new hardware. That’s why you can download OS X for free starting with 10.9 Mavericks (the first version since 10.6 that I’ve used because of this). If your Mac can run Mavericks, Yosemite, or El Capitan, you can have a fairly up-to-date version of Safari, iTunes, and Apple’s other apps.
I can’t understand why Google is doing this. Since when does Google care if Windows XP, Vista, and OS X 10.6, 10.7, and 10.8 are actively supported by Microsoft and Apple? Maybe it’s Google’s development tools that requires Windows 7 or OS X 10.9. Maybe it’s simply that Google Chrome is the most popular browser in the world, so what if you lose a few legacy users?
Our site stats for February, which do skew toward people with older hardware, shows 11.4% of site visitors using an Intel Mac are using OS X 10.6 Snow Leopard, and 6.2% are still on 10.7 Lion, while 10.8 Mountain Lion is in its death throes at just 3.0%. OS X 10.9 Mavericks, just two versions old, is behind Snow Leopard at 8.7%, and 10.10 Yosemite has already dropped from a high of 52% to 18.8% while 10.11 El Capitan accounts for nearly half our Intel Mac traffic at 49%.
Firefox looks like the lone holdout among the big three Mac browser makers. The Mozilla team has not announced its intention to leave behind OS X 10.6 Snow Leopard users, at least not yet. As one of them – I have Snow Leopard on my 2007 Mac mini – I am grateful.
If you use Snow Leopard, Lion, or Mountain Lion, I hope you are grateful as well. Apple’s Safari has abandoned you. Google’s Chrome has abandoned you. But Firefox has not!
If you haven’t tried it lately, maybe this is a good time to check out Firefox 44.
