Image didn't upload first try but second attempt worked; see attached list of browser.newtab settings

See the homepage for that New Tab Override (browser.newtab.url replacement) extension that you have installed. https://addons.mozilla.org/en-US/firefox/addon/new-tab-override/ And view the screenshot of how to set the "Options" for that extension.

IMO, silly to have "Options" hidden in "More", but I have a few other extensions that do it that way, too.

Sorry, I don't use that extension so I'm not 100% sure - but I don't think setting the URL in about:config is the way that is done. That did work prior to the Firefox 41 release; I suspect that preference is just "hanging around" and isn't used any longer. Sorry in advance if I am wrong about that, as I said I don't use that extension, I use New Tab Tools - https://addons.mozilla.org/en-US/firefox/addon/new-tab-tools/ - which has far more features.

Hello, try the extensions.newtaboverride@agenedia.com.url in the url you want (always in about:config).

thanks

Thanks for the suggestion, but I need just a little more detail on the steps you're suggesting. I don't really understand exactly what, "try the extensions..." means I should actually do. I looked at those lines in about:config, but the course of action wasn't obvious.

And after all, I did promise to "Be Careful" before it let me play around. ;-)

Maybe tell me what steps that entails?

The browser.newtab.url pref is no longer supported in Firefox (41+), so it is no longer possible to set the new tab page via this pref.

You can look at this extension to set the new tab page:

• New Tab Override: https://addons.mozilla.org/firefox/addon/new-tab-override/

You can set the new tab URL via the Options/Preferences of the extension on the about:addons page.

You can look at 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/

Classic Theme Restorer includes this feature as well. You find "New tab page url" in the Tabs (2) section.

You can use pages like these:

• the default new tab page with the tiles is about:newtab
• the default home page is about:home
• for a blank page use about:blank
• for Super Start use about:superstart
• use the URL of a web page

See the about:about page for available about pages.

Hello, ONLY because you have the New Tab Override (browser.newtab.url replacement) add-on, try the next :

1. In the Location bar, type about:config and press Enter. The about:config "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. Copy the next bold extensions.newtaboverride@agenedia.com.url and paste it in the search area of about:config tab
4. double-click the preference and now you can see the Enter string value pop-up box
5. type your url : https://www.google.com click OK to save it, close the about:config tab, exit firefox and restart firefox again.

Any luck ?

thanks again

Thanks ideato, that solved it.

Your lead-in, "ONLY because you have the New Tab Override (browser.newtab.url replacement) add-on, try the next" leads me to ask, is there a better way for me to have accomplished this?

I only installed that override as a pretty uninformed shot in the dark to modify the newtab properties.

You are welcome, i'm using the New Tab Override add-on from the first day of the release, for me it is excellent add-on, a must-have for firefox, since the browser.newtab.url pref is no longer supported in Firefox 41+ for security reasons.

thanks again
