New Tab Override does not let me add URL

more options

I've installed the New Tab Override, I go to Add-ons, then Extensions, I click New Tab Override, I click options. There is no drop down menu. There is no ability to customize. The info I see is: Automatic Updates, Last Updated, Homepage and Rating.

I have a screen shot but for some reason cannot upload it

The options page is really long, so you may need to scroll down. Here's what it looked like last year for reference.

This page has changed since I last tested it, so please ignore the screenshot.

Okay, I tested again. The Options page for New Tab Override is a little glitchy. If you switch the extension's status from disabled to enabled on that page, you need to reload the page (Ctrl+r) to show the last two lines. You can use Ctrl+Shift+r to bypass the cached version if Firefox isn't refreshing the page normally.

Ideato - I tried removing and re-installing. Same problem.

jscher2000 - I've tried your steps and I'm getting the same result.

I definitely think I'm doing something wrong but have no idea what! It's probably something simple. I've attached my screen shot so you can see what I see.

I've done this successfully in the past. Feeling frustrated.

If all else fails, try going through the back door:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste tabo and pause while the list is filtered

(3) If the extensions.newtaboverride@agenedia.com.type preference is bolded and "user set" to something other than custom_url, right-click > Reset it to custom_url

(4) Double-click the extensions.newtaboverride@agenedia.com.url preference and enter the desired URL (perhaps easiest to copy/paste it from the address bar on the actual page to avoid typos)

Does that work?

jscher2000 - Unfortunately this hasn't worked either.

It seems (for your system details) that you are in permanent private browsing mode browser.privatebrowsing.autostart is TRUE, any luck if you change it to false ?

ideato - Sorry, I'm not savvy when it comes to this. Where do I locate my browser settings in order to try making that change?

more options

Hi Melzer, you can switch it here:

"3-bar" menu button (or Tools menu) > Options

In the left column, click Privacy. Then on the right side, change to "Firefox will: Use custom settings for history" and uncheck the box for "Always use private browsing mode"

jscher - thanks for the clarification, I've followed these steps, I'm still not able to use new tab override.

I'm at a loss :(

more options

Hi Melzer, some older "full themes" can break various aspects of the Add-ons page, but it doesn't seem that you use such a theme, so I can't figure out why those fields are not displayed.

I also can't think of a reason that the extension itself is failing to implement the settings in about:config.

So is Firefox displaying its own internal about:newtab page in a new tab or is something else appearing there?

There is a rather obscure way to override the page using an "autoconfig" file -- a script you copy into Firefox's program folder -- but it's been a long time since I read the details so I'd have to search around for it if you wanted to try that.
