On March 19 I downloaded the latest version of Firefox. Yes, it works much more quickly, thank you, but now I am unable to shut down. The start button leads to the three choices of stand-by, shut down, or restart. But the shut-down does not take place. In desperation I tried Ctrl/Alt/Delete, without success. Please advise.

Réiteach roghnaithe

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.

You can check if there is still a Firefox process visible in the Windows Task Manager.

Firefox has no impact on computer shut down, you must be having some other computer issues.

Firefox shouldn't be able to cause such a problem. Are you sure, there's nothing else causing the problem?

Anyway, update Firefox to version 28.0 might solve your problem. Please reply back with the results.

Thanks for your help. I can exit using the Firefox button, which I stupidly had been ignoring!
