One of the great things about Mozilla is that it has a built in pop-up remover (you know, we have a problem with pop-upsupdate: we don't have a problem with pop-ups anymore :o).
To turn on Mozilla's pop-up remover:
Go to "File" "Preferences"
Click on "Advanced"
Open "Scripts & Windows"
Now just make sure that "Open unrequested windows" isn't checked
In addition, UpSave Quick Links can now be used as a Mozilla sidebar.
To add the sidebar login to your UpSave account (using Mozilla, of course), go to the "Tools" page, and click "UpSave Quick Links Sidebar".
If you don't see the sidebar already, press F9.
