please help

Hello techn4all

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. Type browser.newtab.url in the search box.
4. Double-click the browser.newtab.url preference and change the url to about:blank

Click OK and close the about:config tab.

thank you

What's irritating about this issue is, I had already done this once, but when I "upgraded" [sic] it forgot my choice for some reason and went back to showing FRU thumbnails again.

HI. I wanted the new tab to open to yahoo.com (Canadian edition) So I followed your advice and instead of putting in "about:blank" I put in "about:http://ca.yahoo.com/" - Well that didn't work. So I looked at what happened and went back and after double clicking on browser.newtab.url, I deleted "about:" so that it looked like "http://ca.yahoo.com/" . Works like a dream. Thanks

That is because you used two "protocols". A "protocol" tells the browser /how/ to fetch something. "http" tells it to fetch it from the web, "file" would tell it to fetch a file off your computer. The protocol "about" is used for built-in things like "blank" that don't need to be fetched at all.
