How can I effectively enlarge font size in Firefox?

My laptop resolution is 1900x1200 so the default font size is very small.

I tried to increase the font size through Preferences>Content>Default font BUT it doesn't work well with a lot of sites. It corrupts the layouts so I had to change it back to default.

Then, I used Ctrl+- for zoom feature but that ruins the quality of images in website, and once you restart the zoom is gone.

So, is there anyway around this?

You can increase the String pref layout.css.devPixelsPerPx from 1.0 to 2.0 in 0.1 steps to see what works best.

In Firefox 3.6 and later this pref is a String value parsed to a float and allows to fine tune the dimensions of all elements more precisely.

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.

Forgive me for replying late, but "layout.css.devPixelsPerPx" is currently -1 in my browser.

Both status and type are empty.

Should I still increase 1.0 or 2.0 myself or is there something wrong with my browser in the first place?

Thank you.
