Just like the title says, if you find yourself squinting to read some of the text on web pages, this might help you out.
In Firefox go to, "Edit", "Preferences", click on the "Content" tab, in the middle of the tab you will see "Fonts and Colors", click on the "Advanced" button, take away the check in " Allow pages to choose their own fonts, instead of my selections above", now just click on the button for "minimum font size", and choose the smallest size font that you can still read. (12 or 13 seems to do the trick for me.)
I did not see this tip posted anywhere and it is one of the fist things I do on a fresh install, I thought some people might benefit from this tip.
