CPU jumps to 50% when exiting Firefox, then stays there. Why?

I am using WinXP and Firefox 26.0. 4GB RAM

From looking at Windows Task Manager I came to realise that Firefox continues to run after Exit. It NEVER closes, and continues to use 50% of CPU. Needed to use End Process.

Then, watching Windows Task Manager some more I discovered that the process was NOT using that CPU while running. Only after Exit did the CPU usage suddenly jump to 50%, and stay there. Only End Process closes Firefox.exe.

Any help or advice appreciated.

Use "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit) to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.

Thanks. But I was already using Exit (rather than clicking the close X), having already read that advice on earlier complaints about similar problems.

Any "next thing to try"?
