Microsoft Edge PDF Reader - signature validation warning for official signatures
Since the last edge update we are running into the following issue, which triggers support tickets on our side. It seems that the edge internal PDF Reader now supports validation of digital PDF signatures. This new feature however is incomplete and causes a lot of confusion for edge users. "Official" signatures are labeled as "Unknown Signature" and "The validity of the signature is still unknown": "Official signatures" means qualified signatures from members of the EUTL - the European trust list as defined in ETSI TS 119 612 („Trusted Lists“): [...] the European Commission publishes a central list with links to the locations where the national trusted lists are published as notified by Member States. This central list, called the List Of Trusted Lists (LOTL), is available in both a human readable format and in a format suitable for automated (machine) processing XML. Parts of the edge PDF reader seems to come from *dobe itself which adds additional confusion since in their products (*dobe reader, acrobat etc) the signatures are correctly verified. They support this list for several years now (next to their own AATL list). I tried to find out whether this feature is 'work-in-progress' or it is a bug however the last published roadmap is quite old and doesn't give helpful information regarding this aspect. So my question is: Is full support of PDF signature validation including support of the EUTL planned and if so when?
Edge Pdf Viewer does not support page=Fit (only FitV or FitH works)
Dear community, I found that the Edge Pdf Viewer does not allow to display a pdf so that its first page fully fits into the window (no part of the PDF is out of the viewport). You can use the following URL to verify: https://creativelab.berkeley.edu/wp-content/uploads/2019/12/1920X1080-HORIZONTAL-template.pdf#page=1&view=Fit Test Case 1 When the window width gets too small, the window will display a horizontal scrollbar instead of scaling the pdf to fit the width: Test Case 2 When the window height gets too small, the window will display a vertical scrollbar instead of scaling the pdf to fit the height: When I use either FitV or FitH, the respective behaviour is as expected. But I need to combine both behaviours, and thus Fit would be the right option, which seems to be ignored by Edge. When I test the same parameters in other Browsers that use a Chromium engine, it works. Microsoft Edge Version 141.0.3537.85 (Official Build) (64-Bit) Windows 11 Thanks for any advice and thoughts! If there is a dedicated place to create a bug report, please let me know.
[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!
Google Play Web apps in Edge
Hi Community, We build quite a lot of Webapps in Managed Google Play and assign those to our Android devices managed in Intune as Dedicated with Entra ID Shared device mode. We run MS Edge as the default browser. Lately we have discovered that Webapps, pointing to web sites where you write text in a input field, especially if the text box is at the bottom of the screen, doesn´t behave as we expect. When the virtual keyboard is activated it often hides the text box, making it impossible to see what you write. If we open Edge and manually browse to the same site, it behaves better. I have also tested to open the Web app in Chrome which works as expected. It doesnt matter if I create the Web app with "Fullscreen" "Standalone" or "Minimal UI" display mode. First image shows the site opened manually in Edge. The textbox is moved above the keyboard Same site opened as a Web app. When activating the keyboard, the text box becomes hidden under the keyboardPWA shortcuts don't keep asociated with window - Linux
I recently upgraded to version140.0.3485.14 (Official build) beta (64-bit) and noticed that my PWA, even if they open correctly in a independent window, don't show the "running window counter" on the taskbar. So, for example, if a open Outlook, the window open and loads the app, but if a I click the icon again, it opens another window, wich is a little annoying. I tried removing the PWA from Edge, rebooting, and installing again, but didn't work. Because the only change I made is updating Edge, I think is related to this build. (too lazy to go back or install the stable release)Firmware Analysis now Generally Available
Back in June, we announced the public preview of firmware analysis, a new capability available through Azure Arc to help organizations gain visibility into the security of their Internet of Things (IoT), Operational Technology (OT), and network devices. Today, we are excited to announce that firmware analysis is generally available (GA) for all Azure customers. In modern industrial environments, firmware security is a foundational requirement. IoT sensors and smart devices collect the data fueling AI-driven insights; if those devices aren’t secure, your data and operational continuity are at risk. During the preview, we heard from many customers who used firmware analysis to shine a light into their device software and address hidden vulnerabilities before attackers or downtime could strike. With general availability, firmware analysis is ready to help organizations fortify the “blind spots” in their infrastructure – from factory-floor sensors to branch office routers – by analyzing the software that runs on those devices. What Firmware Analysis Does for You Firmware analysis examines the low-level software (firmware) that powers IoT, OT and network devices, with no agent required on the device. You can upload a firmware image (for example, an extracted embedded Linux image), and the cloud service performs an automated security inspection. Key features include: Software inventory & vulnerability scanning: The service builds a Software Bill of Materials (SBOM) of components within the firmware and checks each component against known CVEs (Common Vulnerabilities and Exposures). This quickly surfaces any known vulnerabilities in your device’s software stack so you can prioritize patching those issues. Security configuration and hardening check: Firmware analysis evaluates how the firmware binaries are built, looking for security hardening measures (e.g. stack protections, ASLR) or dangerous configurations. If certain best practices are missing, the firmware might be easier to exploit – the tool flags this to inform the device manufacturer or your security team. Credential and secrets discovery: The analysis finds any hard-coded credentials (user accounts/password hashes) present in the firmware, as well as embedded cryptographic material like SSL/TLS certificates or keys. These could pose serious risks – for instance, default passwords that attackers could exploit (recall the Mirai botnet using factory-default creds) are identified so you can mitigate them. Any discovered certificates or keys can indicate potentially insecure design if left in production firmware. Comprehensive report: All security findings – from the Software Bill of Materials (SBOM), list of vulnerabilities to hardening recommendations and exposed secrets – are provided in a detailed report for each firmware image analyzed. This gives device makers and operators actionable intelligence to improve their device security posture. In short, firmware analysis provides deep insights into the contents and security quality of device firmware. It turns opaque firmware into transparent data, helping you answer, “What’s really inside my device software?” so you can address weaknesses proactively. What’s New and Licensing We’ve been hard at work making firmware analysis even better as we move to GA. Based on preview feedback, we’ve addressed bugs, implemented usability suggestions and improved the firmware analysis SDKs, CLI and PowerShell extensions. A new Azure resource called “firmware workspace” now stores analyzed firmware images. Firmware analysis workspaces are currently available as a Free Firmware Analysis Workspace SKU with capacity limits. Getting Started If you have IoT, OT and network devices in your environment, use firmware analysis to test just how secure your devices are. Getting started is easy: access firmware analysis by searching “firmware analysis” in the Azure portal, or access using this link. Onboard your subscription and then upload firmware images for analysis. For a step-by-step tutorial, visit our official documentation. The service currently supports embedded Linux-based images up to 1GB in size. We want to thank all the preview participants who tested firmware analysis and provided feedback. You helped us refine the service for GA and we’re thrilled to make this powerful tool broadly available to help secure IoT, OT and network devices around the world. We can’t wait to see how you put it to work. As always, we value your feedback, so please let us know what you think.
Adblock extensions stop working Edge iOS on clearing browsing data
Ghostery and uBlock Origin Lite are available on Edge iOS as MV3 extensions for ad blocking but they stops working when Clear Browsing Data option is clicked for either time period, Last hour or All Time For making them work, Edge needs to be restarted or extensions need to be re-enabled I request Edge iOS team to fix this issueWhy are some websites buggy with Edge?
Hello, I have been having this issue with a lot of websites with edge lately, at least for a few months. I've tried, resetting to default settings, reinstalling edge, and deleting cookies and cache and this error occurs. It happens a lot of with youtube where I get buggy comments like in the photo with the loading circle and then a lot of comments won't load past a certain point. It's driving me crazy and I'm afraid of having to switch browsers soon, I'm hoping somebody maybe knows what's going on and can assist. I tried it without extensions, same result as well. For other websites sometimes it doesn't load and I have to fully refresh the page like reddit. When this loading glitch happens with youtube, I have to make a new tab then it fixes itself but bugs out after a few videos again.After installing new Edge iPad version 140+ the site cannot be displayed in iframe

We tried: turn off every restriction from Intune - same error. add sites to Edge allowList - same error We cannot find any decription or help on registerAsChildFrameAck. I have very limited hands, cuz the problem is on device of bank. Thanks, Iancannot remove master chief halo theme
Hello, I know this sounds like a very stupid question, but I literally cannot remove this theme for some reason. earlier today, I accidentally clicked on it and didn't think much of it. but now, I can't find the option to remove it 😭 any feedback would be helpful. thanks.
