I have to zoom out to see all of my tiles in my new tab window, how can I get that setting to stay as a default? I have to zoom out every time I open a new tab

Although we haven't discovered the reason for it, you could look into the workarounds discussed there: [https://support.mozilla.org/questions/1025414 How do I change the default zoom for New Tab only?]

What is the setting of the browser.newtab.preload pref on the <b>about:config</b> page? You can try to toggle this pref. Also make sure this pref has the default value. *http://kb.mozillazine.org/browser.zoom.siteSpecific You can open the <b>about:config</b> page via the location/address bar. You can accept the warning and click "I'll be careful" to continue. *http://kb.mozillazine.org/about:config ----- *http://kb.mozillazine.org/Zoom_text_of_web_pages *http://kb.mozillazine.org/browser.zoom.full *http://kb.mozillazine.org/toolkit.zoomManager.zoomValues
