Can you explain the significance of different splitter lines on the Net tab in Firebug?
In this screenshot, line 1 and 2 appear to be grouped together. However, line 3 stands alone.
What do these groupings represent?

What do these groupings represent?
To maintain a manageable scale for the X axis (representing time), the waterfall graph divides the timeline and restarts displaying new requests that begin later in the page's lifespan from the beginning.
Put simply, when a new request starts after a set period of time (default is 1 second) since the previous one finished, it is shown as starting from the beginning of the graph. This prevents the X axis from endlessly expanding, which would hinder readability of the graph.
Each request starting from the beginning creates a distinct group, visually separated by a slightly bolder horizontal line.
The preference extensions.firebug.netPhaseInterval [ms] allows users to specify the interval at which the time break should occur (default is 1000 ms). Setting it to 0 disables this grouping feature altogether.
