It takes me to the Bing website. How do I change the landing page to Google?

Hi,

It sounds like a setting was changed on your new tab page. These changes are usually caused by third-party toolbars or add-ons. I understand that you would like to know how to change it back. Not a problem, please follow the steps below:

1. In the Location bar, type about:config and press Enter. The "This might void your warranty!" warning page may appear.
2. Click I'll be careful, I promise! to continue to the about:config page.
3. Type browser.newtab.url in the search box to find it on the list.
4. Double-click on browser.newtab.url and type in about:newtab in the window that pops up.

Restart Firefox and open a new tab to make sure the change was made. If there is any issues with plugins please also see: Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

Please post back with your results, we are happy to help.

Thanks.

How do I add the thumbnails for previously viewed websites?

Note that your System Details List shows multiple Flash plugins.

• Shockwave Flash 13.0 r0

You can find the installation path of all plugins on the about:plugins page.

You can check the Flash player installation folder for multiple Flash player plugins and remove older version(s) of the plugin (NPSWF32) and possibly (re)install the latest Flash player.

• (32 bit Windows) C:\Windows\System32\Macromed\Flash\
• (64 bit Windows) C:\Windows\SysWOW64\Macromed\Flash\

You can change the order of the boxes on the about:newtab page and drag an item to a different tile to pin it to that position or you can remove a website by clicking the close X to block that URL. You can drag a bookmark or history item and drop them in a tile on the about:newtab page to pin them and have your own favorites sites showing.

Changes made manually on the about:newtab page are stored in prefs that you can find on the about:config page.

• browser.newtabpage.pinned stores websites that you have pinned to a tile.
• browser.newtabpage.blocked stores websites that you have removed by clicking the X button in a tile.
