This addon displays startup timings as exposed by a Gecko API at the about:startup url.
Several timings may be displayed, depending on the platform, the application and its version:
: Gecko main function is entered
: The tabs from the previous session have been created (not loaded)
: Something has been painted in the application (whatever this means)
: The first application top level window was created.
: Custom linker was initialized.
: Custom linker loaded the main libraries.
: Started to load content for the first URI since startup.
