Using Firefox 24.0 on a desktop and laptop, when I open Facebook the Tab title shows the Facebook icon, the number seven in parenthesis (7), and the word Facebook. What does it mean?

For Facebook, that usually means you have 7 notifications. Other sites use it for different things.

Sounds like something added by an extension.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.

The tab usually shows the data designated by the page between the <title> and </title>tags in the head section of the page. This might not might not be displayed in the page itself.

Some sites use a script to update the title of the page to reflect things like unread messages. If you notice the number going down when you read messages or notifications, that could be it.
