For the new tab page, you can use this extension:

https://addons.mozilla.org/firefox/addon/new-tab-override/

After installing the extension, you need to use its Options page to set the desired new tab page (instead of using about:config).

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?

Once you have it set the way you want, you can close the Add-ons page (or use the Back button to return to the Extensions list from that Options page).

Also, can the startup page(s) & homepage be defined seperately?

Hmm, if you want to start with a specific page other than your home page or a blank page, that isn't an option you can set within Firefox. You can modify your desktop shortcut with a url to launch a specific page when you use the shortcut. Or you could start Firefox by using a website (.url) shortcut to a website. If you click and drag from the padlock or globe icon to the desktop, that should create a shortcut to the current page.

Does either of those sound like a usable workaround?

Possibly. My specific problem is that I want to open firefox with 3 pages (ebay, facebook & email), but I want the home page to point to my local webpage.

Hi temp90, try editing the Target attribute in your desktop shortcut with the "startup-only" pages. Right-click the shortcut, then Properties. On the shortcut tab, the Target should be selected. Edit it to match this pattern with the addresses you want.
