A Large Black Band appears across a web page insisting that I download a security fix, no way to close this, and the download is NOT from Firefox.
As stated above - I went to a website story from Yahoo, Shortly after the page displayed, a large black band appeared across the whole screen, covering the requested page. On the left hand side was a large Firefox Logo, in the center of the band the words "Security Allert," and then download the fix or something of that nature. There was no "X" box to clear the message, just a DOWNLOAD button, and a "Technical Details," Button. Being suspicious, I moused over the "Technical Details," button and the URL below appeared as anything but a Firefox website. The URL was so long I was not able to copy it - it extended off the screen.
The only way I could get rid of it (even from the process table) was to do a hard shutdown. When I rebooted, the Yahoo page with the Black FireFox window reappeared. I went to the process table once more to close the message, and the phony page then asked "Do you REALLY want to leave this page?" To which I said yes.
Please help.
Thanks,
Paul
ps: I tried to find the Yahoo Web Page that spawned to black banner to no avail. I couldn't capture the URL of the download website to provide to you either - Sorry

I probably should mention the Ctrl+w and Ctrl+F4 keyboard shortcuts to close the current tab. Pages could intercept those, but they would be worth a try if no other means of closing a tab is available.
You might find the problem site URL in your history. You can use Ctrl+Shift+h or "Show All History" to pull up the Library window.
This could have been just the site, but sometimes an add-on injects bad ads into pages. You can view, disable, and often remove unwanted or unknown extensions on the Add-ons page. Either:
- Ctrl+Shift+a (Mac: Command+Shift+a)
- "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Extensions. Then cast a critical eye over the list on the right side. All extensions are optional, so if in doubt, disable.
Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
That might or might not make a difference, depending on the source of the problem.
If you like, you can change how Firefox recovers from a crash. Instead of automatically restoring the last set of tabs, you can have Firefox ask if you want to restore them all and give the option to avoid opening some of them. Here's how:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.
(2) In the search box above the list, type or paste sess and pause while the list is filtered
(3) Double-click the browser.sessionstore.max_resumed_crashes preference and change its value from 1 to 0 (zero) and click OK
Please be careful not to change other session restore settings so that you can preserve this option for when you really need it.
