Are you talking about the about:newtab page with the tiles?

You can change the order of the boxes on the about:newtab page and drag an item to a different tile to pin it to that position or you can remove a website by clicking the close X to block that URL. You can drag a bookmark or history item from the sidebar and drop it in a tile on the about:newtab page to pin this item and have your own favorites sites present.

Changes made manually on the about:newtab page are stored in prefs that you can find on the about:config page.

• browser.newtabpage.pinned stores websites that you have pinned to a tile.
• browser.newtabpage.blocked stores websites that you have removed by clicking the X button in a tile.

I was talking about the page that comes up on your screen when you start Firefox. That's why I called it the 'Start Page' or whatever.

That's not a newtab. It's the original tab or something.

And you call them 'tiles' I see. I think I've seen them called thumbnails elsewhere. I didn't know what to call them. Mini webpages.

I'll get what I want out of your answer somewhere, I think. It seems very complete. Thanks for that. I'll mark it as 'the answer'. Thanks.

You would normally see the about:home page when you start Firefox unless you have changed the home page setting.

If you do not want to see the currently set home page then change the startup setting:

• Tools > Options > General > Startup: "When Firefox starts":
  "Show my windows and tabs from last time"
  "Show my home page"
  "Show a blank page"

You can check the target line in the Firefox desktop shortcut (right-click: Properties) to make sure that nothing is appended after the path to the Firefox program.

I've been very remiss here. Sorry. I kept referring to my problem as the Start Page and even wrote that second post to emphasize that's what I was on about.

But I'm not. It is the newtab page that I'm on about after all. Why I thought it wasn't I don't know. I'm just going crazy. My 'start page' is simply google and that's fine. But then every new tab is a page full of icons (?) of web sites I've visited.

My problem was that yahoo mail doesn't crop up there though all those other thumbnails (?) of my frequently used sites do.

and yahoo mail is always the first thing I want when I open the browser.

So thanks again. You've answered my question twice, fully and completely and with extras.

Sorry for the hassle.

Well, no, you haven't really. But that'll do. I'm fairly sick of it. There's other hassles, too.
