How do I prevent ads being displayed by some sites when a tab is closed in FF?
For some sites, when closing a FF tab using the [X] button, an ad (usually) or other information is drawn on the browser until I manually select a different tab. The tabs used to automatically display the adjacent tab (not an ad) when a tab is closed. -Regards

Could you test this function in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions, and disable hardware acceleration and some other advanced features of Firefox. More info: Diagnose Firefox issues using Troubleshoot Mode.
You can restart Firefox in Safe Mode using either:
- "3-bar" menu button > "?" button > Restart with Add-ons Disabled
- Help menu > Restart with Add-ons Disabled
Not all add-ons are disabled: Flash and other plugins still run
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (not Reset).
Any difference?
It could be the work of one of your add-ons, or even add / mal-ware. Look thru your add-ons list and make sure you know what each one is there for. Also, check the programs that are on your computer
Windows: Start > Control Panel > Uninstall Programs. Mac: Open the "Applications" folder Linux:
- Ubuntu Unity {web link}
- Xfce: Applications Menu category sections
- options depends on the package manager and the desktop environment
Go thru the list. If you find something that you don't know what it is, use a web search.
