Ogg Vorbis and Opus are free and open-source audio codecs with great quality. They are developed by Xiph.Org Foundation and IETF.
Opus codec provides the best quality (latest listening tests: http://listening-test.coresv.net/results.htm for 96 kbps and http://listening-tests.hydrogenaud.io/igorc/results.html for 64 kbps) and very low latency (http://opus-codec.com/comparison/ ). More information: http://en.wikipedia.org/wiki/Opus_%28audio_format%29 . Support status: http://caniuse.com/#search=opus .
Ogg Vorbis also provides good quality. It is an old audio format and you can find many of Ogg Vorbis files in the web. Ogg Vorbis is very popular in the Linux world.

As arithmetic coding patents for JPEG have now expired, it would be nice to support arithmetic coding in the JPEG. It will allow recompress existing JPEG files using arithmetic coding losslessly, as the result size of all JPEG files will be reduced by 10%.944 votes

H265 aka HEVC is the successor of the H264 video format.
HEVC is said to double the data compression ratio compared to H.264/MPEG-4 AVC at the same level of video quality. It can alternatively be used to provide substantially improved video quality at the same bit rate. It can support 8K UHD and resolutions up to 8192×4320.
What about to support this in Microsoft Edge and IE?178 votes

Most browsers support the ability to drag and drop images from the browser to a folder on your taskbar or on your desktop. This makes it easy to quickly save images from a webpage. The closest thing Edge is able to do now, is making a shortcut to the url of the image. Which of course doesn't help.72 votes

Some things are handled not correctly regarding the HTML5 video abilities:
- IE does not fire the resize event
- no waiting event on buffer underrun
- canplay and canplaythrough events are missing if you seek
- pause event is missing after the playback ends
- seeked event is fired without change of the image (in 86% of all cases)
- timeupdate is fired in waiting state
Please work on a more robust video API. A more elaborated description can be found at http://www.ronpub.com/publications/OJWT-v1i2n01_Hoernig.pdf55 votes
Defines a canvas.captureStream() method allowing real-time capture of a <canvas> element into a MediaStream.
Use cases include local transcoding using the MediaRecorder API, game streaming, lots more.

I work for a large well known Office Products company. Edge is not capable of correctly printing sheets of labels, business cards, and other products because of the inability to print full sized sheets correctly. This is because the "Narrow" margin choice clips the border of the sheet. With a setting of "None" this would be corrected. Google Chrome notices that if a page is exactly the size of the sheet of paper it does not rescale. Scaling of 100% could be applied without any margins. Newer printers are capable of having very small margins and even some print to the edge of the paper. Currently we have to tell our clients to open the document with IE 11 to print it correctly. This should not be a difficult change to implement.

Support h.265 Main profile video codec please

This feature gives developers the ability to access Near Field Communication (NFC) functionality of a device, such as reading and writing NFC tags as well as exchanging data between NFC capable devices.
In IE, there was print templates to manage printing pages. Like MeadCo ScriptX ActiveX plugin, we need to be able to do everthing programmatically that can be achieved with print dialog and print templates. It would be great if it becomes HTML5 specification too.(Raw Printing should also be included).34 votes
Please add support for Media Source Extensions to Internet Explorer 11 on Windows 7. This update will match what is currently available using Chrome or Firefox.
In addition it is very confusing that this feature is available on IE 11 with Windows 8 and 10 but not 7.30 votes

A user is prompted for permissions to access the microphone *each* *time* they access a page that calls getUserMedia().
This is makes web apps that are used regularly essentially unusable, because the user permissions dialog pops up at every page load.
Both FF and Chrome support persistent user permissions.13 votes
All major browsers support data uri for images, audio and video. IE only supports it for images.
