User(s) can reproduce this bug
The MaintainScrollPositionOnPostback page directive does not work correctly with Mozilla Firefox 4. On a postback the scroll position reverts to the top of the page.
Details (expand)

Visual Studio/Team Foundation Server/.NET Framework Tooling version

Visual Studio 2010 SP1

Steps to reproduce

Add the MaintainScrollPositionOnPostback="true" directive to the top of a page. Perform a postback, note that the position reverts to the top.

Note that usage of this in your browser definition file corrects the problem:
<browsers>
    <browser id="Firefox4" parentID="Firefox">
        <identification>
            <capability name="majorversion" match="4" />
        </identification>
        <capabilities>
            <capability name="supportsMaintainScrollPositionOnPostback" value="true" />
        </capabilities>
    </browser>
</browsers>

.NET when shipped supported FireFox up 3.x, the next version of the framework will be future proofed supporting all future versions of Firefox. Until then the workaround associated with this connect item will solve the issue but you might want to add an entry for version 5 as well.
