Why all of these HTML5 features are turned off in the last few builds of Edge canary?

[HotCakeX]

1. Web Cryptography API
2. Content Security Policy 1
3. Audio track selection
4. Video track selection
5. ObjectRTC API for WebRTC
6. Enumerate devices
7. Screen Capture
8. Access the webcam
9. Credential Management

I compared the current Edge canary Version 83.0.478.0 (Official build) canary (64-bit)

with the results of a previous version:

https://techcommunity.microsoft.com/t5/discussions/very-impressive-edge-insider-canary-results-in-ht...

Edge now scores 473

http://html5test.com/

I haven't disabled any flags, I'm using the same flags that I have always enabled, there are of course more flags enabled right now than there were before but nothing disabled by me.

the score has been that low in the past 2 weeks, so you can say since the past 5-6 canary builds.

[#2]

Interestingly, for me the base score (default canary with no flags) is 528, way higher than 473.

I temporary disabled all flags by launching edge with '--no-experiments'

If I leave the flags enabled the score rises to 533.

[#3]

Canary builds are to test and introduce bugs and experiment the features
and they are not obligated to explain the changes :)

i'm glad it's finally downwarded your expectations

That's only your opinion which is not true. Edge team have been very nice so far answering to users issues.

[#6]

Strange, I have those enabled as well, except a few about Omnibox.

You could find a full list of enabled flags plus command line switches at "edge://gpu".

under the 'Version Information' section in front of 'Command Line'.

Perhaps something else has been causing it.

so I did a mistake there, at first i thought i ran that switch but i put it accidentally between "default" which is the profile name and Edge created another profile for me and in that profile the score was okay.

however later I tested by using that switch properly but this time the score remained low.

I also tested in InPrivate mode window and the score remained low.

so whatever it is, it's in my Edge profile settings, it's not related to cache/cookies etc.

I'll keep digging

[#8]

Between the 2 Edge profiles that generate different scores, contents of "edge://gpu" are the same except for the "Data exported" parameter which is basically the date.

I went over all the settings and they are identical between 2 profiles. I disabled all of the extensions too just to be sure.

there isn't much I can think of at this point.
currently the only difference between the 2 profiles is that one is connected to my Microsoft account and the other one is offline but I don't see how it can disable 9 HTML5 features..

[#9]

Actually, it disables 55 features. Closest thing I could relate are GPO's; maybe group policies set for your account are causing this?

[#10]

I haven't installed the group policy files for the new Edge yet and just ran "rsop.msc" to confirm no Edge-related policy is interfering.

also I'm using Windows insider fast ring as always.

[#11]

@HotCakeX  Hmmm, this is all really interesting... I'm asking the team and will let you know if they have any suggestions. Have you seen any other changes in performance? And which build(s) are being affected?

[#12]

Hi, thank you very much that will be great because I'm totally clueless :)
I can't be sure I'm seeing any performance effects, because it's been like that for a while..
currently i'm on Edge Version 83.0.478.1 (Official build) canary (64-bit)

btw I recently reset my Windows using cloud download and I remember before doing that, the problem was still there.

So, to sum it up

here is the screenshot.

1. on the left side it's my Edge profile connected to my Microsoft account.
2. on the right side it's my Edge profile that is offline, not connected to any online accounts.
3. in Edge, profiles share the same flags.
4. both profiles have identical settings.
5. there is no group policy affecting Edge canary.
6. group policy files for the new Edge are not installed.
7. I'm using Windows 10 insider fast ring latest build (19603)
8. both Edge profiles have the same content in their edge://gpu/ report (compared the texts with a program)

[#13]

@HotCakeX I've found the problem and solution. The site html5.com is categorized as insecure so Edge blocks a lot of features to protect you.

I downloaded an extension to give me https everywhere and this is the new score:
