Once again, nobody is denying anything about memory problems. But there are two things at play here: 1. One person's experience is not universal. With a web browser as customizable as Firefox, there will be certain configurations causing problems that aren't caught by tests or by dogfooding. Some people are probably seeing leaks that users with a default configuration don't see. For example: https://blog.mozilla.org/nnethercote/2014/08/15/the-story-of-a-tricky-bug/ https://blog.mozilla.org/nnethercote/2014/08/15/the-story-of... 2. People need to report their problems in ways that are actionable. HN is not a bug tracker. If somebody on HN (Hacker News! News for programmers who presumably know how a bug tracker works!) is having memory issues, (s)he should have no problems filing a bug in Bugzilla. Firefox has had about:memory for years now; save that report and attach it to your bug.
