The image did not post with my original question. Here is a screen shot of the nag screen I keep getting.

Hmm, I can't recall seeing that one.

Usually websites record your action on a dialog in a cookie. Have you changed the default cookie settings in a way that might limit what cookies Yahoo could set?

In case the problem is corrupted cached files or cookies... When you have a problem with one particular site that previously worked normally, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

(1) Clear Firefox's Cache

See: How to clear the Firefox cache

If you have a large hard drive, this might take a few minutes.

(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:

• right-click and choose View Page Info > Security > "View Cookies"
• (menu bar) Tools > Page Info > Security > "View Cookies"
• click the padlock or globe icon in the address bar > More Information > "View Cookies"

In the dialog that opens, you can remove the site's cookies individually. You'll notice for yahoo.com that there are a lot of cookies for various subdomains; some of those might not be relevant to problems occurring on news.yahoo.com, but it's probably okay to just remove those as well.

Then try reloading the page. Does that help?

I tried the clear cache and the remove cookies suggestions. Neither of them helped. However, I right clicked on the nag screen and selected show page source. I found the entry div id="yset-search-upsell-container". Further down I selected the entry and used AdBlock Plus to hide it. Next, I went back to news.yahoo.com and clicked on several news articles and the nag popup did not appear. I hope this is a permanent fix!

Just ran into this on my Dads machine ... solved it by:

Windows: Tools -> Options -> Privacy -> History -> "Use Custom Settings" -> and UNCHECK "Always use private browsing mode"

Linux: Edit -> Preferences -> Privacy -> History -> "Use Custom Settings" -> and UNCHECK "Always use private browsing mode"
