If you open more than one tab in Safari running on Windows 7, they show up as if there are multiple windows, while technically, they are not windows, just tabs inside one window.

I think this behavior is not usual compared with other browsers like Firefox or Chrome or any other application for that matter.

Any idea why this happens or is this a bug?

Safari version: 4.0.4

Have you managed to get around this bug ("feature") somehow? – Hugo Mar 28 '12 at 13:34

This is by design. Each tab gets its own thumbnail preview in the Taskbar, so you can switch faster to the desired tab.

Internet Explorer 8 does the same, and it's possible with Firefox 3.6 too: Unlock thumbnail previews for Firefox 3.6 on Windows 7

Internet Explorer 8:

Firefox 3.6:

Apparently it's foreseen in the version 5.x of Google Chrome.

This is a taskbar enhancement that is available in Windows 7 for applications that are Windows 7 aware and can inform the OS that there are internal contexts that can benefit from displaying multiple views to the taskbar. Chrome and older versions of Firefox don't do this but IE8, Office 10 apps, Firefox 3.6 and the current version of Safari do. Newer version of apps wil lincreasingly support this and other Windows 7 Superbar features like context menu jumplists.

Actually, firefox doesn't do this by default, you have to manually enable this mis-feature. – Hugo Mar 28 '12 at 13:33

As found on

Run Safari in XPSP3 compatibility mode as administrator to make it behave properly.

You can set the Safari program properties to run in Vista (SP2) computability:

You do not need to select the "Run this program as an administrator" as reported in an earlier post.

This may be a design feature of Windows 7 (one that I do not like) however even IE9 allows you to disable this in the Internet Options.

You need 10 reputation to be able to post images. However, you can just upload the image to any hosting site and link to it in your answer, and someone will come along sooner or later and embed it as an image. – Indrek Sep 26 '12 at 22:10
