Mozilla Question

[OnyxCougar]

Ok, so I'm at home and I DL'ed Mozilla Firebird and Thunderbird. I really wanna give this a shot. So I'm going through my settings, trying to get acclimated, and I see this:

Open external links in new windows or tabs

If another program wants to display a web page in the default browser, Mozilla Firebird will reuse an existing window by default, which means that it will navigate from a page you might be reading. To stop this, add the following code to your user.js file:
// Stop reusing active windows:
user_pref("advanced.system.supportDDEExec", false);

What about new tabs instead of windows then? If you prefer tabs instead of windows, you must also install Tabbrowser Extensions, a very powerful extension that enhances the functionality of the tabbed browsing. After installing the extension, follow these instructions (make sure you didn't forget to add the above code to your user.js file):

1. Make sure you didn't forget to add the above code to your user.js file.
2. Select Tools > Options > Extensions, select Tabbrowser Extensions and click Settings.
3. Expand the Category list and select the topmost sub-item (it's supposed to read Advanced Tabbed Browsing but the Category list is too narrow).
4. In the Window Mode drop-down listbox, select Use multiple browsers only when I open them.

Done! Now any link opened by an external program, such as your e-mail client, will open in new tabs.

Well, it didn't work. I closed the browser and reopened, just in case, (because the whole toolbar customization taught me to close and restart the browser when you change something). Still nothing. When I click on my cellar subscription notification, it replaces my home page, not opens a new tab. Which I really really want it to do.

Any suggestions?
