And I value FF way more than an hour of battery.

All day every day my computer works fine.

That difference in battery, if it exists, doesn't actually materially manifest anywhere. But the difference between FF and anything else matters basically every minute all day.

On top of that, even if I ever did actually run into the difference, needing to plug in before I would have anyway, it's an annoyance vs a necessity. The ability to control my own browser is frankly just not negotiable. It doesn't actually matter if it were less convenient in some other way, it's simply a base level requirement and anything that doesn't provide that doesn't matter what other qualities it might have.

You might say "a computer that's dead doesn't work at all" but that never actually happens. I'd need an 8 hour bus ride with no seat power to get to the point where that last missing hour would actually leave me with no computer for an hour, and that would need to be a commute that happens twice every day for it to even matter.

For me that's just not the reasonable priority.
