Mozilla is comprised of a lot of different people working on a lot of different things. There are people focusing on various memory and speed issues, but they can't (and shouldn't) allocate all their resources to focusing on just a few issues.

yarou obviously didn't say that they should focus everyone only on reducing Firefox's memory usage and performance problems. I'm not sure how you mistakenly got that impression, because that's clearly not what that comments suggests.

The main issue here is that we've been hearing that these problems will be fixed, or even that they supposedly have been fixed, yet they're still present years later.

Whatever work is being done clearly isn't having much of an impact. Users are still reporting problems with Firefox's performance and memory usage, even if those within the Mozilla community wish to deny these problems exist, or claim that they'll be fixed "soon".

Users can only take so much of this. With Chrome and Firefox offering UIs that are pretty much identical these days, but Chrome offering significantly better performance and significantly lower memory usage, any reasonable user will obviously consider switching from Firefox to Chrome. Many have done so already, and many will continue to do so as time goes on.

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.
