How do I enlarge the print on the screen, e.g., to 125% or 150%?

Using FireFox, my email and other web sites show up with print that is too small for me to read comfortably. I installed Theme Font & Size Changer. However, when I engage it via its icon at the upper right corner of my screen and increase the point size, it changes only the size of the drop-down box but has no impact on what I'm trying to read!!!

What am I missing here?

Have you tried to change the font size with Ctrl++ (resp. decrease it with Ctrl+-). See The article on Zooming the web pages for more.

Let us know if it helped.

Control + works like a charm! Many thanks.

You can use an extension to set a default font size and page zoom on web pages.

I installed the "Default FullZoom Level," but, after restarting Firefox, no new icon or other means appeared by which I could actually adjust the screen size as described.
