Note: Firefox 22 now has a Network Timeline which is deeply integrated and is in continuous development. Thus I am planning to stop working on this add-on in order to better spend time on other add-ons and maybe fixing bugs related to the inbuilt network timeline. Thanks for all your support and using this add-on.
Graphical Timeline is a new and interesting way of debugging in Firefox. It visually displays the events happening in your browser in real-time. Currently events like Network calls, DOM events, and memory collections events are being tracked. More will follow as I continue the development of this Developer Tool.
To use the developer tool, simply choose 'Graphical Timeline' from Web Developer Menu under Firefox menu or Tools Menu. (or hit Ctrl + Shift + Q). Click the record button to start capturing the events.
for more updates.
This is a total work in progress, so feel free to shout out any issue on this
