Using Windows XT and running FF 4.0 (Yahoo Edition 1.8), I am asked to download "the update", but the "application" never seems to take. Is something blocking it?
After the download, the application screen just shows the "green worm" running across the top for many minutes until I either "hide" it or X it out.

There is a 4.0.1 update for Firefox 4.0. I don't know why automatic update isn't working for you, but you could try these troubleshooting articles and cor-el's post in the earlier thread:

Software Update - MozillaZine Knowledge Base
Any luck?
