>Remember that decade where Firefox shed market share to Chrome for being too "slow" and "bloated"?

The only part I remember where Firefox was notably slower was videos when Google led Firefox for a ring around the rosie when they singlehandedly decided to use a proprietary codec for their youtube videoplayer after first making everyone believe they were working on using a different one which FF started working on supporting. I can't count the amount of complaints i heard of firefox being slow there.
