Edge user here. For one, chromium is faster than firefox, any given page will load about 20% faster, another reason is edge workspaces feature, I've grown to like it, which seems to be some sort of chromium feature that everyone bakes in weird ways if at all, and I'm still running ublock origin on edge without any funky bypasses.

Then there's a fact that a bunch of sites/webapps straight up refuse to work on firefox and they ask you to install chrome or something. And lastly chromium the most popular browser flavor and as a web dev it helps to see pages through "the same eyes" as my users/customers.

That's about it, the only reason I use firefox every day is their superior picture-in-picture player, chromium one is waaay inferior.

To access Edge Workspaces, you’ll need a desktop running Windows 10, Windows 11, or Mac OS, Microsoft Edge version 144 or later, and to be signed into Microsoft Edge with a Microsoft (MSA) account or Microsoft Entra ID / Azure Active Directory (AAD) account.[1]

This is rare in my experience. And most were fixed with an extension to change the user agent string. Or were for amusement and used a new Chrome feature. Or used a feature Mozilla rejected for security and there were alternatives.

I'm skeptical; You're probably measuring Chromium + ads against FF + ads.

The only fair test is testing agains FF + uBlockOrigin. And there, FF wins hands down.

I'm hardcore FF, and it used to be a bit slower than Chrome, but nowadays the difference is barely noticeable. And on very large pages (e.g. big tables), Chrome is a lot slower than FF.

Give Vivaldi a try. I used edge on windows and android ever since it started used chromium, and switched to Vivaldi on Linux and android 8 months ago. Generally quite happy with it - not really missing any features from edge.
