Hello insiders!  Today we released build to the Microsoft Edge Dev Channel.  As promised last week, this is the first release out of the version 78 branch, and quite fittingly, it’s packed with new features and fixes.  Some of the most significant ones include:

  • Fixed an issue where dragging and dropping IE mode tabs will sometimes cause them to show the wrong zoom level.
  • Fixed an issue where the Downloads page cuts off its content when the window size decreases instead of resizing it.
  • Fixed an issue where the sync confirmation dialog isn’t wide enough to fit its contents.
  • Fixed an issue where some browser pages like Favorites don’t get dark or light theme applied until the page is refreshed.
  • Improved the light theme in the F12 Dev Tools.
  • Fixed an issue where some icons like the new tab page icon aren’t properly updating to a lighter color when the browser is switched to dark theme.
  • Fixed an issue where the buttons on the PDF toolbar don’t change state when you interact with them.

Good news!

Testing... :)

Good news! Thanks! Testing... :)

We lost the ability to sync to Work Accounts.
It was working fine in the last build.

@Deleted The same thing happened here... In the previous version, we had a working sync for our Azure AD identities. With this update, it displays the "sync is not enabled for school or work accounts" message again... Is this intended behavior?

@josh_bodner So glad to finally see the Share button! Will I ask too much if demand the option to always show it on the toolbar, like in the old Edge?

@josh_bodnerNetflix player is still buggy.

@Deleted, @AndreLengton syncing for work accounts is currently under a controlled rollout, which is why it hasn't been mentioned in the release notes yet either.  

"Fixed an issue where items on the Favorites Bar sometimes don’t respond to clicks when a folder is open."

Thank you.
thanks for the clarification.

@josh_bodner Excellent, in the last update, there was an error that broke the searching bar, making my search results displayed in Bing instead it's fixed.


Still waiting until you can add the option to make this as our default browser, so I can get rid of Google Chrome.

Can't you do that in the computer settings? Edge Dev is offered as an option to be the default web browser in Settings>Apps>Default Apps>Web Browser in my laptop Windows 10.

The right-click menus over tabs and the tab bar still say 'R eopen closed tab' instead of 'Reopen closed tab'.

@josh_bodner under the new "Read aloud getting better with the cloud," you mention the "Settings & more" menu.  When I click the three dots I see "Settings" but not "Settings & more."  Am I misunderstanding or missing something?  Thanks!

@galaxytechsolutions  If you hover the pointer over the three dots and read the tooltip, rather than click on it, it says 'Settings & more'.

Gotcha, thanks!
Yup, that's how I did it. I find Edge Dev uses way less system resources than chrome, especially when streaming video - so I made it default asap!

@SOI_7 I'm not seeing any "Share" button on Edge Dev. Where is this?

@josh_bodner thanks, IE mode is working as intended again!

@josh_bodner  Something I was reminded of, earlier today, when I'd reported a bug in an extension that's available for both Google Chrome and Firefox, and the Chrome version also works in Edge Dev, installed from the Google Chrome Store. I agreed to check and report back on the hopefully fixed version the developer very quickly produced and put up to both the Firefox and Google Chrome extension stores.


In Firefox, quite reasonably, there is a 'check for updates' to click on in the Firefox Extension page. In Google Chrome, quite weirdly, there is no 'update' control to check for updates for extensions unless you enable 'Developer mode' - for no good reason I can think of, and I can imagine many ordinary users (a) would be wary of enabling something called that, and (b) wouldn't even think that might produce a 'check for updates' button anyway.


I see Edge Dev is following Google Chrome in this at the moment and I had to enable 'Developer Mode' to get an 'update' button for extensions to then get the updated extension I wanted to test (and it was fixed). I really cannot see any reason for or logic in the extension update button being hidden behind 'developer mode'. Could you please just put the extension update check button out in the regular extension page, and not follow Google in this silliness.
