Edge beta crashes after 5 seconds on some old versions of Windows 10
We have problems with Edge Beta versions 151.0.4129.15, 151.0.4129.21 and 151.0.4129.35. On launch Microsoft Edge briefly opens and then closes (like in 5 seconds) on Windows 10 RS1/RS2/RS3. I can't reproduce problem on other versions of Windows 10, such as TH1 or RS4
Solution for PWAs not appearing as separate apps on Linux taskbars
Hi everyone, I recently Installed Microsoft Edge stable on Kubuntu Linux, and I ran into some problems using Progressive Web Applications (PWAs). Launch one Edge PWA (say, Microsoft Teams). It appears normally. Launch a second PWA (say, Microsoft Outlook). Both windows — and every PWA you launch afterward — collapse into a single taskbar group under the first PWA’s icon, identified as msedge. Pinned PWA launchers never show as running. Pinning a running PWA window produces a generic page icon that launches the bare Edge browser when clicked. Launching a PWA from the application menu briefly shows the launcher’s startup placeholder in the taskbar, which then disappears and is replaced by a separate, unassociated entry. This isn’t KDE-specific. GNOME users have also reported issues. After some troubleshooting with Claude, the issues were traced to a mismatch between how the PWAs are identified in the .desktop PWA launchers created by Edge and the app ids reported to Wayland, starting in September 2025, when Wayland was used by default. Identifier Value Example (Microsoft Outlook) Window app_id (native Wayland) msedge-_<appid>-Default msedge-_lkkahpbimdkjdjjiijflmhaeameegbcm-Default Desktop entry filename msedge-<appid>-Default msedge-lkkahpbimdkjdjjiijflmhaeameegbcm-Default StartupWMClass= in that file crx__<appid> crx__lkkahpbimdkjdjjiijflmhaeameegbcm So the solution is StartupWMClass in the .desktop launcher for the PWA to the Wayland app_id. I have a simple Bash script that will do this for all currently installed PWAs as a workaround, but the automod removed that post the last time I tried to post it. The suggested fix for Microsoft This should be a small change to Edge’s desktop-entry generation on Linux: write the Wayland app_id (msedge-_<appid>-<profile>) into StartupWMClass=, or better, make the window app_id match the desktop entry basename per the freedesktop convention. No compositor-side changes are needed — the verified workaround above demonstrates that. I’ve reported this through Edge’s in-browser feedback tool (Alt+Shift+I) with the full diagnosis. If you’re affected, sending your own feedback referencing the same details is the best way to get it prioritized — the in-browser channel is what reaches the Edge team’s triage.
[Wayland] PWAs no longer appear as separate app windows — all group under main Edge icon
Hi, Since around 2025-09-07 to 2025-09-10, I’ve noticed that on GNOME (Wayland) all installed PWAs (even across different profiles) now appear grouped under the main Edge browser icon in the GNOME Shell dash/taskbar. Previously, each PWA would open in its own window group with its own icon. This is still the behavior in Chromium/Brave/Chrome, and can be restored there by editing the PWA’s .desktop file to set: StartupWMClass=<same value as Icon> However, Edge now seems to ignore StartupWMClass completely on Wayland, breaking workspace separation and making task switching hard. Environment: Ubuntu 25.04 GNOME 48.0 / Mutter (Wayland) Kernel 6.14.0-29 Intel Iris Xe GPU Edge (latest stable, observed post 2025-09-13) Repro steps: Install any PWA (e.g. Outlook, Teams, Spotify) from Edge Launch it (from any profile) Observe that it appears grouped under the main Edge browser icon Expected: PWA shows under its own icon and window group like in Chromium-based browsers Actual: All PWAs are bundled into the main Edge window group Editing StartupWMClass in the .desktop file no longer helps This regression makes PWAs much harder to manage on Wayland. Please route to the Linux/Wayland team if possible. Thanks!Edge version 150 JavaScript speechSynthesis.getVoices() undefined voices
For the past few days JavaScript speechSynthesis has had a problem in Edge browser. Sometimes it gets the proper list of voices but most of the time it returns: "Microsoft undefined Online (Natural) - undefined" for every single Natural voice. It then uses the default voice (Microsoft David) for speaking the utterance. Can you fix this bug? Edge Version 150.0.4078.83 (Official build) (64-bit) Thank you.Edge Block/Add Site Notification - How to Disable with GPO?
Hello, I haven't been able to find answers anywhere so far to figuring this out. Currently looking into using GPO for disabling the Block/Allow to send site notifications tabs found in Privacy, search, and services -> Site permissions -> All permissions -> Notifications. I have been able to block to turn off notifications for all websites by default and block the "Ask before sending" notification settings in the same menu as mentioned above. I did so by creating a GPO with the following settings: Computer Configuration -> Policies -> Administrative Templates -> Microsoft Edge -> Content Settings After navigating to this folder, I opened the "Default Notification Setting" setting. Inside of it I switched it to Enabled and Don't allow any site to show Desktop notifications. I have already looked at the "Allow notifications on specific sites" and the "Block notifications on specific sites" settings, however these just allow you to add websites that you want to block or allow that the user cannot remove. I have discovered that putting a wildcard "*" into the "Block notifications on specific sites" settings values will not allow the user to add any more sites to the list. However this still leaves the user to add any site they wish to the "Allow notifications from specific sites" setting, which is the main concern considering all sites should have notifications disabled. Has anyone else had this problem and found a solution or workaround? This works in Chrome, but Edge has been difficult Thanks.
New Canary Edge issue
Since the latest update to .4157 on Canary Edge the browser window behavior has changed. I always have 2 browsers open, Edge Canary and AOL. I can switch easily between the 2 from the Taskbar. Starting today if I go to AOL and then try to go back to Canary instead of opening the whole browser it gives me the option of going back to 2 of 3 browser tabs I have open. What has changed?
Can't see 'line focus' option
Hi all, I find the fade of the background in Edge frustrating as it dims the images and wanted to remove the fade (or make the images remain in focus). I thought maybe the 'line focus' option would help, but I can't find it in my browser. I click 'reading mode (F9)', but see no option for 'reading preferences' in the top bar - instead I see what I've attached. I'm using Version 150.0.4078.48 (Official build) (64-bit). Can anyone please help?Regression: Vertical tabs no longer collapse in fullscreen (F11) after latest Edge update
After the latest Microsoft Edge update, the vertical tab sidebar no longer collapses when entering fullscreen mode (F11). Previously, when fullscreen was enabled, the vertical tabs would automatically collapse or hide, allowing the webpage to use the full screen space. Now the vertical tab bar remains visible, reducing usable screen area. Steps to reproduce: Enable Vertical Tabs in Microsoft Edge Open any website Press F11 to enter fullscreen mode Observe that the vertical tab sidebar remains visible Expected behavior: Vertical tabs should collapse or automatically hide in fullscreen mode, as they did in earlier versions. Actual behavior: The vertical tab sidebar stays visible during fullscreen instead of collapsing. Additional testing: Tested in a Guest profile (fresh profile with default settings); issue still occurs Happens across different websites Restarting Edge does not fix the issue Edge version: 145.0.3800.58 (Official build) (64-bit)
Edge constantly purges itself
At least twice a month, Edge seems to purge everything. All of my history is gone, all of my accounts are logged out (and do not have username suggestions when logging back in), sites have been reset from dark theme to light, etc. I am the only person with access to this computer and am not wiping the history or anything myself. Why does it keep doing this? How do I stop it?
