<style type="text/css">
html {overflow-y: scroll;}
</style>

I see vertical scroll bars on the pages that are longer than one screen. If you want the bar ''all the time'', you need to add a style rule to your site: <br>&lt;style type="text/css"> html {overflow-y: scroll;} &lt;/style> If you don't see scroll bars even on long pages, perhaps one of your add-ons is interfering? Also, when you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site. 1. Clear Firefox's Cache orange Firefox button ''or'' Tools menu > Options > Advanced On the Network mini-tab > Offline Storage : "Clear Now" 2. If needed, delete the site's cookies here While viewing a page on the site, right-click and choose View Page Info > Security > "View Cookies" Then try reloading the page. Does that help?
