Dev channel build is live

Elliot Kirk

Hello Insiders!  Today we released build to the Microsoft Edge Developer channel.  We’ve got some new features, many of which you’ve seen over the past week in Canary and have been eagerly waiting for in Dev.  Additionally, we have now turned on several new languages on the insider website and added an Enterprise page with offline installer and policy samples.  We’ve also fixed quite a few reliability and behavior issues, the most significant of which include:

  • Added more strings to the translation work
  • Prevent IE-Mode in Application Guard containers
  • Ability to set text size and background theme in Reading View is now under flag.
  • Ability to use dark mode on downlevel Windows versions 7, 8 & 8.1
  • Search box now clears content with Esc or “x” button

Fixes for improved reliability: 

  • Fixed a crash on Extensions page.
  • Fixed a crash in API keys
  • Fixed a crash while opening PDFs
  • Fix crash in Sync service
  • Fix crash due to cached call in renderer
  • Fix deadlock in Windows, where Microsoft Edge blocks shutdown.
  • Fix crash in JSON parser

Fixes for improved behavior:

  • Fix preventing URL redirection in Application Guard.
  • Fix to prevent creation of database until needed (performance)
  • Subpage headers display the number of search results.
  • Fix to close Profile UI on sign-in
  • Dev Tools support using OS theme color on Windows 10
  • Fix color contrast for selected favorites
  • Fixed Copy / Paste keyboard shortcuts on macOS

  • Fix for data imports from Chrome and Edge during First Run experience.

@Elliot Kirk  Oh, yellow icon of favorites folders were better :-(. Please help distinguish folders from websites without icon. Why not using yellow icon for folders everywhere - you use it in Windows, OneDrive, why don't use it in Favorites in Edge?

Or give us control as to which icon we want to use on an individual choice.... I personally like the yellow, so let me choose the yellow.. Those that like the white, let them choose it...... This is really a small thing when we are actually trying to get this ready for public release, but it is a thought for when the public gets it....

Also, how about letting us show icon only for the folders as well....

Maybe because they look ugly and heterogenous in black and white Edge design with blue accents and line-based icons? Explorer allows you as many colors as you wish but screaming yellow is only for the canary Edge icon.



Definitely would love the option of turning every bookmark into icons, rather then having to right click everything just to turn them into icons. 

@Elliot Kirk  


This is excellent work some really good fixes, Edge is becoming the best and fastest browser out there.


Well done all, for all the hard work. 

@Elliot Kirk Hey, you made pinned tabs wider! Thank you!

@Elliot Kirk thank you for remove the yellow favorite folders. The standard (no color) favorite folders looks great in favorites bar! :) 

Definitely not, the standard (no color) favorite folders looks great! :) 

I agree with you too much colour gets confusing. its not needed.

Anyone know if they've fixed the issue with bookmarks/favorite not syncing across multiple devices (all on the same - latest- Windows 10 build and also Edge dev build -latest-)?
For last weeks I have to manually export and import bookmarks which is little annoying.
Also, sometimes, Edge hangs up during import of bookmarks and spike the CPU up to 60 - 80% until I force kill in task manager.

I have macbook it's first time rid of safari and using another browser I used to use safari on macbook and google chrome on windows now I use edge on both I love it even bing I give it another chance its results not duplicated 

I downloaded Edge Dev last night and saw an instant improvement over the original Edge for OS10. I am honored to be a part of the guinea pig trial group. Thanks. I don't do many intricate things, but when the simple things are accelerated, it is amazing.





Totally agree with you Drew it will fly out, and knock all the others off their perch.




Gerry, it's SO nice to see someone write my name without @ & 1903.  See how it's done Folks?  It's easy to be traditional & customary, in spite of tech automation. :smiling_face_with_smiling_eyes::thumbs_up::thumbs_up:


@Elliot Kirk 

Oh Elliot,


Switch to IE, suddenly, isn't showing (in ellipsis) in latest Dev & Canary... even, with IE integration flags enabled.  I, for one, have reported it to :)


There are some issues I'm having when using Edge with Narrator. It seems to be sluggish, and up arrowing on pages causes the narrator cursor to get stuck at times. It was crashing with Narrator before but not with this build. Other screen readers such as Jaws 2019 work fine.

@tojtojka Agree. The standard Windows yellow folder makes them stand apart from website icons much better than a "outline" style icon. Being faster to visually ID is also a positive accessibility factor

@solitonmedic  That would be awesome!


The speedbump to that is when sites have similar icons.  Maybe, if both existed, all & individual, so name could show if & when necessary to distinguish between similar ones.


Where is IE mode? It’s just disappeared when I have upgraded to new version.



After upgrade to, IE Mode completely disappears. #edge-internet-explorer-integration = IEMode, but there is no menu item to show page in IE.
Tell me please, how IEMode works now?





@welzewool @Kyle_Wu @Elliot Kirk 

This is a known issue. Everyone keep reporting it to Mr. :)  It surely will be corrected soon.


@welzewool Also missing that option here. Pretty much the main reason to use the new Edge at work... :(


Hi ____,

It's sounding as if everyone has the same issue.  The Team has been notified & likely will have this rectified asap.  But, still, submit it to :) The more instances & data they have the better.  And it's both Dev and Canary.

Btw, for "at work" IE is, always, available in Win10; without any need for Edge C.  Start > Windows Accessories (folder) > IE. Can (then) be pinned to taskbar.


Hi Drew


IE is being phased out of Edge slowly but surely, as it progresses to the New phase of Edge, eventually Edge will be a stand alone browser, without dependencies on Chrome or any other, It will be a completely new all singing all dancing whoopee browser.

I am blind and I use Dolphin Supernova without any glitches at all.  Well done Microsoft, I have no accessibility problems at all.  



@Elliot Kirk  hey please add built-in vpn and data saver for people who have limited bandwith

Mr Authentic


I totally agree with you on the VPN aspect, as it is needed by all on the Internet, its always a very expensive commodity just for basic security protection, something that Microsoft could do well looking into, especially in today's climate of cyber crime.

In the new TAB, there is an exception in the news stream when it opens.

BetterSnapTool on macos does not work with Edge browser. Is there any way to fix this? @Elliot Kirk 

Yep, same issue encountered, no more IE mode in the menus



I dunno.  I'd like to think so.  But I can say, as a front line IT guy for a few thousand, I still get this a LOT:

"What's Edge?"  MOST people are not going to rush out to upgrade.  MOST people don't even know what this is or why they should care.  Or not.  Those that aren't FF or Chrome dedicated users will use the default browser whatever that may be.  This is very likely the huge majority.  So I'M hoping that Edgium will be the new default by 1909.  I like the direction this browser is headed.  Kudos to the dev team here.  Good job so far


Hi everyone is that only me here who has problem with LastPass extension? it works for a few days then it stops for some reasons and then again i reinstalling it and again and again since i have this browser. Any update for this in the future?


@Elliot Kirk 

I quite liked the new checkbox, dropdown and button style that came with the previous dev build. It makes it stands out from Chromium.



No I have the same problem with TweakPass, but my last post on that was deleted, it works in Edge but not Edge C.

@tojtojka I know favorite folders are landscaped and favorites are portrait but i agree with would be nice if folders were a different color.

The visual corruption issues I kept having, especially when using video or browsing compositing heavy sites, disappeared with the last dev build (211) and are still gone with this one. Whatever happened, glad it did! Thanks.

As much as I hated those yellow folders at first, I kind of want them back now. The current ones (outline icon) simply don't look good.

@Deleted @Elliot Kirk 

I'll be more blunt.  Whose silly idea are these ridiculous looking outlines?:exclamation_mark::thumbs_down: Put back the proper looking, almost realistic looking approach that WAS there:exclamation_mark:  Stop trying to improve what doesn't need mucking about with it.  If it ain't broke don't fix it.  There is heaps that does need to be done.  Don't spend time or effort on things that are fine 'as is". These outlines look SO dumb, geeeesh :face_with_rolling_eyes:



Lol :>The Folder icon is an interesting thing… I mean, All of the other icons in newEdge are outline style - such as the feedback, all of the icons in the main menu area, and the “no icon” page icon. However, the folder icon is located among all of the icons for other websites, so it seems out of place - so here’s my problem. If it is a filled-in, yellow icon, then it doesn’t fit with the rest of the iconography of the browser, but if it is an outline, it doesn’t really fit in with the icons of all of the other webpages. So maybe there needs to be a different solution… However, the color of the icons right now probably doesn’t need to be crazy priority as the final UI does not seem to be a really big focus right now as the developers are still working on support for other features (such as sync). We’ll see what happens, but for now i’m just glad the favorites is not just a long list of text.

When will the browser launch fully and become the real EDGE or will it just stay in dev stage?

Some of us reckon It may well be pushed out with 1909. Certainly, do not / would not expect it before that. But, it is replacing, current, Edge; will not be just betas forever.

Please try to add the video pop-out feature like in Opera Browser, it is really a very convenient feature@Elliot Kirk 

I absolutely DISAGREE!! It is much more difficult to differentiate between links and folders. Please, please KEEP the yellow folders or at least make it an option

@Simon Raihani 

I know some people (because humans hate change) have a hard time to accept & live with things that are a little different than the past.  But, much as people sometimes hate hearing it said, that is what we must do sometimes.  Sometimes we have to take things and live with them whether they are how we think they should be or not.  Then, it's a matter of run with because it is what it is OR run with it begrudgingly because it is what it is.
