Microsoft Edge UI Now 40% Faster on Average, Key UI Elements Load Up to 4x Quicker
Microsoft has launched a major update for its Edge browser, reducing key feature load times to achieve a global First Contentful Paint (FCP) of under 300 ms. FCP refers to the time between when a user initiates navigation and when the browser displays the first part of the content from the Document Object Model (DOM). Studies show that delays exceeding the 300 to 400 ms range can lead to noticeable drops in user satisfaction, so reaching this new threshold should make the browser feel more fluid and engaging for everyday use. To meet the target, the Edge team leveraged its proprietary WebUI 2.0 architecture instead of React. By emphasizing native web components, such as HTML templates and CSS styling, rather than relying heavily on JavaScript at startup, they achieved a 40% average reduction in load times across thirteen core features.
Microsoft tested the settings UI with the new update, showing a 4x improvement in that specific case with WebUI 2.0, compared to the older React page. Users can now access the Settings page, invoke Read Aloud voice playback, switch between Split Screen views, and manage Workspaces with minimal delay, even on lower-end devices. This release builds upon the significant improvements delivered in May 2024 with Edge 122, which produced launch times 42-76% faster, depending on hardware, and a February 2025 optimization targeting fourteen interface subsystems. Internal tests confirm that the settings panel, which was once a slight performance bottleneck, now consistently renders in under 300 ms across a wide range of machines. Microsoft also plans to extend these enhancements to Print Preview, Extensions management, and other elements through the remainder of 2025. Below is the 4x improvement in the Settings page UI.

There are no doubt some issues with sites implicitly (or explicitly. Staring at you, Youtube) favouring chromium over ff, but A. This is not the norm. And B. this counts for FF, not against it. Monopoly is bad, and all that.
Mozilla is very flawed, but they would need to pull a PRISM-grade scandal to even come close to Google, Microsoft, and co. Netizens should be critical of them, but let's at least first take a look at these mires we call markets that we've driven ourselves into.
Edit: Speaking of forum rules, I really need to stop derailing threads. :|
I guess I can download and try…
i just decided to use Edge for “DualShock calibration GUI”… i use google search in safari and firefox, so google “knows” me… lol.
so given a choice i will not use Chrome.
EDIT: Also, I specifically stated the portable version, not the installed version. The portable version runs as is described, portable. Nothing is installed or alters your Windows config in any way you do not choose.
