hello, firefox 22 is now respecting the pixel density you've set on a system level in the windows control panel. more information about that is available at http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/display_use_large_or_small_fonts.mspx if you want to set the text size/pixel density in firefox different from that of your system's settings like it was handled in prior versions, enter '''about:config''' into the firefox address bar (confirm the info message in case it shows up) & search for the preference named '''layout.css.devPixelsPerPx'''. double-click it and change its value to '''1.0''' (or any other zoom factor that fits your purpose; -1.0 is the default value and will adhere to the system settings).
