my father is running firefox and his screen aligns to the right any ideas as to what he needs to do?
When my father loads any screen in Firefox what you would expect to see in the centre of the screen is instead on the right hand side as a result what you wouldnmormally see on the right hand side is missing.

If you have increased the minimum font size then try the default setting "none" as a high value can cause issues like you described.
- Tools > Options > Content : Fonts & Colors > Advanced > Minimum Font Size (none)
- Tools > Options > Content : Fonts & Colors > Advanced > [X] "Allow pages to choose their own fonts, instead of my selections above"
This issue can also be caused by an extension that isn't working properly.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
