Status: RESOLVED DUPLICATE of bug 289182

(Firefox :: Tabbed Browser, defect)

Description

[Caleb]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050427 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050427 Firefox/1.0+

Currently, if you open an image (in the current tab) Firefox will show a
thumbnail of it in the tab's caption, but if the tab loads in the background,
the thumbnail won't show.

Reproduction:
1. Middle-click (open in background tab) on this link:
https://bugzilla.mozilla.org/attachment.cgi?id=181657
2. Wait for it to load completely

When it finishes loading you will notice that the tab has no thumbnail of that
image.

To get the expected results you will have to focus that tab, refresh the page
and wait for it to completely load, and only then you will see the thumbnail.

Reproducible: Always
