Description

3 years ago
User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:43.0) Gecko/20100101 Firefox/43.0
Build ID: 20150915030232

Steps to reproduce:

Add a prefetch hint to HTML head with the following code:

    `<link rel="prefetch" href="/fonts/Fira-master/woff/FiraSans-Regular.woff">`

The file is also called, as intended, in a CSS file to be served as webfont.


Actual results:

DevTools Network panel shows the resource three times (1x for the CSS load and for whatever reason the preload hint is appearing twice I assume) and counts page weight with three occurrences.


Expected results:

Network panel should only show the one downloaded font (if it’s not a core bug in Firefox and it’s downloaded 3x actually). It should take the file only once into account for page weight.

Ideally, the panel indicates that it’s been downloaded through a prefetch hint.

Read triple as twice please. Sorry, the one additional was my fault.
