What is the timing of this suspicious tab appearing?

• Any new window (e.g., Ctrl+n): your home page may have been modified. You should be able to edit that in the Options dialog. Startup, home page, tabs, and download settings. If your change doesn't stick between startups of Firefox, check for a user.js file which might dynamically alter your startup settings. See this article for more information: How to fix preferences that won't save.

• Startup only: some malware has been discovered to modify the target of the desktop shortcut used to start Firefox (adding a URL to open). Right-click the shortcut > Properties > Shortcut tab, check the target and make sure it is just the path to firefox.exe and doesn't have any additional parameters after that.

• Time of day: some malware has been discovered to create a scheduled task that will launch a page in your default browser at a particular time. You can check here: Start button > Control Panel > System and Security > Administrative Tools > Task Scheduler

• Other: you may have rogue software running continuously on your system. Please try the scanning/cleaning tools listed in this support article: Troubleshoot Firefox issues caused by malware.
