988687 - Display favicon preview for small PDFs

Status: RESOLVED DUPLICATE of bug 988686

(Firefox :: PDF Viewer, defect, P3)

Description

[Jennifer Morrow [:Boriss] (UX)]

This is an engineering counterpart to bug 960940, which describes the user experience decision behind this behavior.

Currently, if a PDF is open in a tab and no domain favicon is available, Firefox shows no favicon in the tab.

If that PDF is smaller than pref browser.chrome.image_icons.max_size, we should show a scaled preview of that PDF, the same as we do for other images smaller than pref browser.chrome.image_icons.max_size.  We should show this preview even if a domain favicon is available.

Acceptance Criteria:

Favicon is shown on tabs open with PDFs smaller than pref browser.chrome.image_icons.max_size

Seems like this would be implemented in PDF.js and should be filed on Github (https://github.com/mozilla/pdf.js/issues) where PDF.js work happens.
