MemChaser is a Firefox extension which keeps track of the garbage collector activity and memory usage.
You can install the currently released version of MemChaser by visiting the addon page and following the prompts.
MemChaser adds a widget to the addons bar, which dynamically displays the resident memory usage, the length of the last interactive GC and CC, and the time elapsed between the two most recent of these. For more information on each component simple hover over for a handy tooltip.
By clicking the widget you will activate a menu. From here you can trigger a CC or GC, or reduce the memory currently in use. You can also start/stop the logging from here, or open the log folder.
The logging uses the Statistics API to write full details of each GC.
First you will need to clone the repository:
git clone https://github.com/mozilla/memchaser.git
You will then have to init the Add-ons SDK submodule.
git submodule update --init
