Have tried using Ctrl+N but no new window opens. Any website requesting a new window to open function fails.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.

See:

If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.

  • Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
  • Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Your above posted system details show multiple Java Console extensions.
You can uninstall (remove) the Java Console extensions and disable the Java Quick Starter extension, you do not need them to run Java applets.

See http://kb.mozillazine.org/Java#Multiple_Java_Console_extensions

Disable the Java Quick Starter extension: Tools -> Add-ons -> Extensions
Control Panel -> Java -> Advanced tab -> Miscellaneous -> Java Quick Starter (disable)
