> Kitchen sink software is bad software.
Ah yes. That's why Chrome bravely refuses to be a kitchen sink. It only has a small set of available APIs like USB, MIDI, Serial, Sensors (Ambient Light, Gyroscopes etc.), HID, Bluetooth, Barcode detection, Battery Status, Device Memory, Credential Management, three different file APIs, Gamepads, three different background sync APIs, NFC...
And it still doesn't support alternate stylesheets, maybe due to NIH syndrome.
Firefox killed the alternate stylesheet UI in like version 1. Nobody really supports alternate stylesheets.
Can you explain what you mean? My Firefox version supports setting alternate stylesheets just fine. It doesn't persist across page reloads, which is annoying though.
