Microsoft Edge 140 has been released. It brings a handful of new features.
Let me very briefly mention the AI features in the update. Edge now supports GPT-5 as an option for Copilot Smart Mode. Users can create a podcast with Copilot in Edge. You can create images and videos by typing your query in the address bar, and Edge will generate the media using DALL-E 3, Open AI's Sora.
With that out the way, let's discuss the more important features. The release notes for Edge 140 says that Microsoft Edge has a new security feature called Scareware blocker. This is an AI powered option, which uses a local model, to protect users from scareware attacks like tech scams that trick victims into believing their computer is damaged, luring them into calling a fake support line, which could then lead to the PC remotely taken over by attackers. If Edge identifies a website as a potential tech scam site, it will display a warning on the screen, block access to the website, and offer an option to close the page, or continue browsing.
Scareware blocker in Edge is not enabled by default. You can manage Scareware blocker from Edge's Settings > Privacy, search, and services / Security. Or use this shortcut to jump to the option directly: edge://settings/privacy/security?form=MT0159
Here's the official feature page for Scareware blocker.
Edge 140 brings another security feature called HTTPS-first mode. Google introduced this feature in Chrome in September 2023. HTTPS-first mode tells Microsoft Edge to automatically upgrade insecure HTTP connections to HTTPS when possible. If a site doesn’t support HTTPS, the browser will display a warning pointing out that it is a security risk. According to Microsoft's announcement, this feature only works for public sites, and not on private ones, or URLs that the user entered manually.
The option is not enabled by default. To manage the feature, head to Settings > Privacy, search, and services / Security > and toggle the option that says "Automatically switch to more secure connections with Automatic HTTPS".
Microsoft Edge now saves tab groups automatically, to allow users to resume browsing quickly. Tab groups that were organized manually are also saved for revisits, after restarting the browser. Admins can manage this feature using the SyncTypesListDisabled policy with the “openTabs” data type.
Reddit user Kotaless says that Edge removed the RTX Video Super Resolution (VSR) flag, which uses AI to enhances the quality of streaming videos on NVIDIA's 40 and 30 Series GPUs. The user said that disabling a setting will allow the feature to work, as it will allow NVIDIA to take over the enhancement work. Go to System and Performance > System > and toggle "Enhance videos".
Edge 140 includes security patches from Chromium, and one Microsoft Edge specific security vulnerability has also been patched. It is tracked under CVE-2025-53791, and has a medium severity rating. The security issue, described as a security feature bypass vulnerability, which could allow an attacker to bypass a security feature over a network. This improper access control in Microsoft Edge involves a hacker to enable Edge Split Screen mode, have a specific configuration, and run multiple pages. The attack vector could lead to the threat actor running scripts to read a token from a web page's iframe, make changes to the javascript in the window. Microsoft has credited Mingi Jung with WebSec for reporting the issue.
The new features are available in Microsoft Edge 140.0.3485.54.
