Remember when the whole reason people liked Firefox is that it was super customizable? There was a time when it was THE power user browser. Things only went sideways after Chrome came out.

Firefox literally was a mainstream browser at one point. Internet Explorer sucked. Safari didn't suck but it was nobody's favorite either except some really hard-core Apple fans.

Yes, Chrome was revolutionary when it came out. And yes, Firefox seemed to struggle with legacy architectural decisions that limited their ability to catch up. But Firefox was still differentiated and had a loyal fan base. Loyal fan base is exactly what can keep a project or product alive through a downturn. All they had to do was focus on the browser. They did some great things along the way like popularizing DoH. But it's 2025 and there's still no UI for switching profiles that any normal person might be able or want to use. Can you really blame people for giving up?
