Firefox
Also, any idea how to just generally make stuff bigger on my display, just switched over to my 60" TV and everything's so smaaaaall~~
I'm guessing resolution?
You should have your resolution to a nice size (preferably max for your monitor) and just increase the DPI on your font.
Personalization > (left panel) Adjust font size (DPI) > Change it to large or custom one.
As for firefox, not sure how to make a zoom permanent. I never change it except to reset if I accidentally change it.
