Body of invoice moved to right since Fiirefox 3.0.2 upgrade

Fields Bill To, Invoice # and Item have all moved to the right by some inches within Invoice Details since Fiirefox 3.0.2 upgrade.
This may have more to do with Firefox/Addons rather than Zoho Invoice and curious if anyone else has this issue and what causes it/how to fix.
