Firefox 17.0 was released on Tuesday, November 20, 2012, with a number of security issues fixed. You should update to the current version. *Updating Firefox - https://support.mozilla.org/en-US/kb/update-firefox-latest-version *Latest release version full installer - https://www.mozilla.org/en-US/firefox/all.html ------------------------------- NoScript updates frequently and the NoScript update page can be turned off. *Turn off NoScript update page: **Open NoScript Options - hover your mouse over the NoScript icon and choose "Options" **Click the "Notifications" tab and un-check "Display the release notes on update" at the bottom of that display **Click "OK" to close the NoScript Options panel ------------------------------------ If you are using a security application (firewall/av) with a virtualization or sandboxing feature or an application like Sandboxie, updates to Firefox and its Add-ons (and other applications running in the sandbox/virtual environment) never actually get installed outside of the sandbox/virtual environment. You should disable the sandbox/virtualization before running the updates.
