Open issues/risks

`

Stage 1: Definition

1. Feature overview

Ultimately, we want to be able to provide tools that give Firefox users answers to the following questions:

1. is my page taking a lot of memory?
2. if it is, how do I fix it? (where is that memory going?)
3. am I allocating too many objects? if so, where?

For the first stage, we need to identify:

1. what information we can get from the system presently
2. what work needs to be done to get the information required to answer the questions above

The goal of this project now is to get the ball rolling so that the backend can provide the information we want so that a future release can provide the user-visible tooling.

2. Users & use cases

`

3. Dependencies

Other Documentation

The Eclipse Memory Analyzer Tool provides comprehensive views into memory usage on the Java platform. Ideally, we would provide more distilled information than this, but the MAT represents a much more robust tool than anything we've seen for JavaScript presently.
