I'm running UNR 10.04 on an Acer Aspire Z8 and I've never been able to have webpages display correctly in Firefox (v.3.6.11). Many webpages just never quite seem to fit the screen, with the horizontal scroll bar often having to be used. Example image below on the Betfair site. It doesn't happen with all sites but enough for it to be a little annoying.

Any advice/help appreciated.
