There's a hidden setting for new tabs; as you've noticed, they don't automatically follow your home page setting. (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful. (2) In the search box above the list, type or paste '''newtab''' and pause while the list is filtered (3) Double-click the '''browser.newtab.url''' preference and enter your preferred page: * ''Page thumbnails (default)'' => about:newtab * ''Blank tab'' => about:blank * ''Built-in Firefox home page'' => about:home * ''Any other page'' => full URL to the page Press Command+t to open a new tab and verify that it worked. Fixed? Two gotchas: * If Firefox ignores the setting, one of your extensions may be overriding it. You can review, disable, and/or remove extensions on the add-ons page:<br><br>Tools menu > Add-ons > ''in the left column click'' Extensions * If the change works but at the next startup is back to Bing, you might have a user.js file in your personal Firefox settings folder (your Firefox profile folder). This article describes how to track down and remove the file: [[How to fix preferences that won't save]]. Any luck?
