Are you always changing the text zoom level when you open a new browser window? Do you find some sites you visit have impossibly small fonts and you are constantly changing your text zoom back and forth as you visit different sites?

NoSquint is a Firefox extension that allows you to adjust the default text zoom level, which is very useful if you have a small display or run at a very high resolution. NoSquint also remembers the zoom level per site (though you can disable that). Until website designers (typically those who know of no life outside Internet Explorer) who insist on using font-size: 50% are administered a harsh LARTing, NoSquint exists to make web browsing tolerable in Firefox.
