Since last weekend (8 aug) I see to be getting an increasing amount of javascript problems. This is about the same time to obnoxious spinner was introduced (see T108365 about killing that one). Symptoms:
- Stupid spinner popping up after page load
- Authority control not working half of the time
- Firefox complaining about scripts not responding
- Javascript seems to be eating loads of cpu cycles
