Very Impressive Edge insider Canary Results in HTML5 Test (Plus other browsers) Comparison
Here is the the score of browsers to see how much of HTML5 technologies and features they support.
In order of highest to lowest.
Edge insider Canary Version 79.0.286.0 (Official build) canary (64-bit) Highest Score
Google Chrome Canary Version 79.0.3924.0 (Official Build) canary (64-bit)
FireFox version 71.0a1 (2019-09-26) (64-bit)
Edge classic (EdgeHTML)
Microsoft EdgeHTML 18.18990
Microsoft Edge 44.18990.1.0
Internet explorer 11 version 11.1.18990
Internet Explorer 11 (latest version) obviously has the worst score, but it's the only browser that can manage to get the perfect 100/100 score from Acid3 test among all these browsers tested. the rest of the browsers can only get 97/100.
By the way, Acid3 is an old test.
Comment down below what you think. I for one am hella impressed by Microsoft Edge insider's score!

Okay I just did another test right now
Windows 10 x64 insider fast ring build 19033
Edge insider Version 80.0.346.0 (Official build) canary (64-bit)
turning on "Experimental Web Platform features" flag boosts the score by 5 points
you know what's the worst part about that website? it's too stupid that it can't tell the difference between Google Chrome and Edge insider browser.
Chrome dev. heh!
Edge insider has been around for 8 months at least but they don't recognize it yet
- we're running the same version, i wonder why i have such a low score
- Not sure, I always used Canary version, maybe some feature are online turned on in Canary
So what caused the Edge insider Canary to get the score of 543 and Not the Perfect score of 555?
here is the list of features and HTML5 capabilities that are not supported (as stated by that website: https://html5test.com/ ) in the browser.
- MPEG-4 ASP support
- H.265 support
- Dynamic Adaptive Streaming / MPEG-DASH
- HTTP Live Streaming / HLS
- JPEG-XR support
- Custom content handlers
- Script execution events
- Writable streams
there are however other things that the website is failing to detect (thus marking them as unsupported) even though I enabled them using flags, such as
- Web Authentication / FIDO 2
- FileSystem API
Very helpful website to find out which technology is supported in which browsers
https://caniuse.com/#search=h.265
technologies like
- H.265 (already supported in Edge classic)
- MPEG-DASH (already supported in Edge classic)
- JPEG XR (already supported in Edge classic and Internet Explorer!)
- and it's a technology developed by Microsoft which is superior to older formats like PNG and JPG.
the thing is, Edge classic supports a set of technologies that the new Edge doesn't. on the other hand, the new Edge supports some technologies that the Edge classic doesn't. so if you merge them together you'll create the best of the both worlds browser ^^
