This is nice in theory, but literally never have I heard a friend saying "I tried using Firefox, but it was too slow / too power hungry / had bad sandboxing / wasn't configurable enough". Not once. What I did hear, tens of times, is "I just use X, it came preinstalled with my phone/laptop. Why should I switch?"

I actually have seen this in my current company. Many developers switched browsers away from Firefox. Some even switched to Edge since it plays better with the battery. I know early adopters of Brave from its early years too.

When things get a bit bigger in JIRA, Firefox's JS engine struggles with horrifying amount of JS JIRA throws at it. Same for Google Meet and Zoom.

I tried and realized Firefox has a huge power consumption penalty on my Android phones and a considerable one on my laptop. I still keep it as a secondary but it is still not there yet.

IT people in my both current and previous company prefer deploying Google Chrome. Previous one was a complete Microsoft shop, they didn't use the built-in Edge but removed it and deployed Chrome. There is quite a bit Microsoft sysadmin know-how about Chrome, less for Edge and even less so for Firefox.

If you're privacy-conscious you'd have searched or visited blogs like this[1] or privacyguides.org or privacytools.io. They all point out issues.

They are all a factor. Many people still install Chrome because the apps / websites they visit tell them so. If you used web-based engineering software, they will always recommend Chrome.

Google Docs of course works better on Chrome, intentionally or unintentionally Google will roll out more optimizations for it.

Sorry, I should have made it clear: my comment is about the general population. It is about why Firefox is losing market share. Not about IT people, privacy-conscious people or alike. It is about why the average Joe stopped isn't using Firefox.

I use Firefox because of the multiaccount containers. But it really burns CPU cycles on my Mac, it’s insane. Even with tabs unloading automatically and everything. I don’t get it.

Chrome is not perfect but it’s significantly lighter on the battery. Safari is the lightest on Mac but the addons suck.

Memory-wise I found both to be just as bad.

Occasionally I get things that don't work in Firefox that do work in Chrome. I don't have a comprehensive list for such instances but I'm sure that's a contributor as well. uBlock Origin on mobile keeps me using FF.

I am actually only switching to Chromium based browsers because some corps and most notably some captcha/paywalls don't work as expected. But the. I always think I made the right choice (actually I am rather using Zen because I love their UX on top of FF)
