Hello Tcalp, yes from 41 the browser.newtab.url preference is abused and should be removed (bug Bug 1118285)

try to install the next add-on : New Tab Override (browser.newtab.url replacement), and after that, modify (double-click on it) the next preference

• [email protected]

to about:newtab

probably now you are able again to set your pages.

thank you

Hello, for unknown reason, this add-on does not work for me. Any ideal what happen? Reinstalled Firefox 41 and repeatedly downloaded this add-on but still not working. Any ideal ?

If an extension that modifies the new tab page isn't working then you might have multiple extensions installed that try to set the new tab page and they might not be compatible with each other.

Classic Theme Restorer includes this feature as well. In current CTR versions (1.3.9+) you find "New tab page url" in the Tabs (1) section.

There is this extension if you use the home page as the new tab page.

• New Tab Homepage: https://addons.mozilla.org/firefox/addon/new-tab-homepage/

You can use these special pages for the new tab page or use the URL of a web page. the default new tab page with the tiles is about:newtab

• the default home page is about:home
• for a blank page you can use about:blank
• for Super Start you can use about:superstart

I just want Google.com as new tab page, don't need homepage for every new tab. browser.newtab.url in about:config is "Google.com". However, the extension override looks like following:

[email protected] [email protected] [email protected] [email protected] [email protected] [email protected]

The first 5 extension status is "user set", the 6th is "default" and value is "about:newtab". Is these first 5 extension causing the trouble because of multiple downloaded? Can I just delete the first 5 extensions and leave 6th ?

Hi mingy1, it sounds as though you just need to change the last preference to the page you want. Or you can use the interactive settings page as described below, but I don't think you should delete the other preferences .

Open the Add-ons page using either:

• Ctrl+Shift+a (Mac: Cmd+Shift+a)
• "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Extensions. Then on the right side, find New Tab Override and click its Options button. (See first screen shot attached.)

Depending on the height of your screen, you may need to scroll down to enter the desired address into the form. (See second screen shot attached.) For example:

• Page thumbnails (default) => about:newtab
• Blank tab => about:blank
• Built-in Firefox home page => about:home
• Any other page => full URL to the page

Then tab or click away from that form field and you can test using Ctrl+t.

Success?

Hi jscher200, thanks for instruction. It (the second screen) was default to "about:newtab" and it brings up the tiles although browser.newtab.url in about:config is set to "Google.com". When I changed to full URL "Google.com", it's finally working as I want to bring up the old fashion Google search engine for new tab. So the tricky is 1) download the New Tab Override (browser.newtab.url replacement) 2) modify (double-click on it) the next preference,

   [email protected], 

to (URL you want), not "about:newtab".

Thanks so much for your information.
