Orgs can do multiple things at the same time.

In principle this is true. In the concrete case of Firefox, they have proven they focus more on side quests than on making a quality browser.

I lost any hope they'll go for technical excellence instead of virtue signaling and branding after the Brendan Eich disaster. They feel now like a Microsoft, Google, Apple, or any other big corp.

I used Firefox since it was called Firebird and finally gave up and switched to another (non big corp) browser and couldn't be happier.
