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.

Also, they're comparing Edge before vs Edge now, not Edge vs others.
Wait till they find out how fast it would go if they stop logging every action and shoving in a boatload of "features!"
I really hate using EDGE on my refurbished notebook. So many ads which slows donw the ryzen 4650u pro processor. Vivaldi which is also based on chromium / chrome works much better.
I think librewolf will be faster. I'll test that again. I'm not sure how i can test that without external hardware on a ryzen 4650u pro laptop.
use firefox, and if and the web site is “ill”, switch to chrome for that site.
but, if you need chrome lets say for the “ DualShock calibration GUI” i do not use chrome i use the lesser of two “evils”, edge. (actually the only time I don’t use Firefox, because that program will not work in Firefox and I need that program more than I need my be beliefs, lol, sarcasm)
masochismUngoogled Chromium or even vanilla Chromium?I'm currently on Opera, but Opera's commercial nature is starting to bug me more than just a bit. On my next scheduled maintenance cycle and OS reinstall, I plan on moving all my machines to Brave, permanently.

The reason FF is trailing in marketshare isn't necessarily that it's a bad product. If Mozilla was half as vile as Google or Microsoft, I dare say they would be in a far better position today.
You don't see everyone using Librewolf or Ungoogled Chromium because privacy extremism doesn't sell even for the total price of zero.
