Is there a way to set a default zoom factor?

I am running firefox on a media center PC attached to a HD flat-panel TV. Due to the high spatial resolution of the display device, and the relatively large viewing distance, opening web pages with a zoom factor of 1 is inadequate. It would be great if I could set a default zoom factor to use when a new web page is opened for the first time. I used 'about:config' to set 'zoom.minPercent' and 'zoom.maxPercent' to larger values. However, these parameters apparently only take effect when the zoom factor is changed for a page, and seem to be ignored when a new page is openened. And, of course, what I really want to set is not a range of allowed values, but a default value instead.

If it is only in firefox that you have problems the layout.css.devPixelsPerPx can be changed. (That at least works in Windows systems see this thread ; changing the interface as well as the content )

There are also addons that may help, but unfortunately possibly not Linux compatible types.

If it is all of your GUI including when you are using the machine offline then you may need to look at Linux, but I assume that is bound to have methods for changing screen appearance and resolution.
