yarou's comment is in response to a presentation about unrelated features, and his/her response suggests knowledge that Mozilla isn't focusing on memory and performance problems.

Many of the memory leaks have been fixed over the years, benchmarks suggest [Firefox can compete with Chrome in terms of speed](www.tomshardware.com/reviews/chrome-27-firefox-21-opera-next,3534-12.html), and Mozilla, realizing their UI still feels sluggish, launched a project (called Snappy) to fight this UI sluggishness.

Many improvements have been made over the years on all counts.
