Why does Firefox not close on mac?

If Firefox isn't closing on a Mac, it could be due to several reasons, such as an unresponsive tab or extension that is preventing the browser from shutting down properly. Sometimes, background processes or tasks may keep the application active. Force quitting Firefox through the Activity Monitor or using the "Force Quit" option can help resolve the issue. Additionally, ensuring that Firefox is updated to the latest version may prevent such problems in the future.
