FF scroll issues with next/previous

[jutzig]

When jumping between translations that have lots of entries in the tools section (e.g. similar translations) firefox keeps scrolling to the bottom of the page.
That is really annoying, because the property can in worst case no longer be seen.
It works fine in chromium though (not tested in any other browser).

To reproduce try "workspace/jenkins/master/de/core/src/main/resources/hudson/Messages_de.properties?key=Util.minute"
