Pick Firefox if
You want an open-source browser that is not built on Chrome’s engine.
The catch. A few web apps are tested in Chrome first, and it runs Firefox add-ons rather than Chrome extensions.
Firefox vs Edge
Firefox is best for an independent, open-source engine. Edge is best for Windows and Microsoft 365.
Pick Edge if
Your work runs on Microsoft 365 or you want sleeping tabs that save memory.
The catch. It nudges you toward Microsoft’s services and Copilot, and it blocks trackers but not ads.
