Firefox is the web browser equivalent a dying language. It will be a tragic loss for the culture of the web for Firefox to fade away. But, there are powerful macro forces pushing us to that outcome. "Switch, please," calls to action are a noble but insufficient countermeasure.
Average people probably don't care about the latest features but Google pushes Chrome very aggressively, so they end up using it anyway.
What annoys me the most, however, is that several things simply don't work in Firefox and the associated report is over a decade old, so with close to zero chances of ever getting addressed. Copying the content of a canvas element as an image to the clipboard is one of these things. In Chrome, this takes a right and a left click. Firefox didn't have such a basic feature last time I checked. There used to be a workaround, opening a blob URL in a new tab and then copy that, but this got broken later, I believe by a stricter security policy.
Firefox is essentially the browser equivalent of Fairphone. It's the most ethical option but it inconveniences you left, right, and center.
