TV stations have annoyingly different volume levels and websites have differing font sizes. The NoSquint addon for Firefox remembers your preferences and adjusts font size and even color on a per site basis. Another addon we’ve used for years and highly recommend.
Firefox does this already without an extension. go into about:config and look for the entry “browser.zoom.siteSpecific” and set it to true. Firefox now remembers your zoom settings for each site you visit.
Thanks for that, anomaly. If you change the zoom setting to true, other features of NoSquint will no longer function.
