I did a bit of digging about my font size issue in firefox between my F20-x86 notebook and my F22 arm setups.
I see that my notebook is using arial for its default font and this works well with the netgear gateway. I don't see arial as a choice on my arm firefox setups. I did some more digging using yumex (slow to start, I am supposing it is the slow I/O to the SD card) and see that the liberation fonts are suppose to provide the arial equiv. But serif is the default font and its size is wrong.
So I saw that wine provides an arial font. I installed wine-arial-fonts and restarted firefox, but still no arial font available to select.
I will have to move this notebook behind the netgear to see if it has any problems, as it is F21-x86 with serif as the default firefox font.
Any pointers, though, on getting arial available in firefox or what is the real equiv?
