That appears to be a problem with a Kaspersky add-on for Firefox. A check on the Kaspersky forums recommended uninstalling and re-installing Kaspersky.
You can also try disabling the Kaspersky extension in Firefox to see if it helps. In the Tools menu select Add-ons. Go to the Extensions section, click on the Kaspersky extension in the list, then click on Disable. If the proiblem goes away when you restart Firefox it will confirm that this add-on is causing the problem.
