Make Firefox automatically set zoom level for new webpages

The Firefox addon NoSquint allows you to adjust the text-only and full-page (both text and images) zoom levels as well as color settings both globally (for all sites) and per site.

This is user configurable from Firefox, without the need for any add-ons.

1. In the address line, type: about:config

2. Scroll down or search for the preference name: browser.zoom.siteSpecific

3. Double-click to change the value to false

Now your zoom settings will carry over from site to site.
