As soon as my FF was upgraded I tried to close one of the tabs I had opened... I click on the X and doesn't close, i right clicked to open a drop down to select close tab and am able to select it bu simply will not close.

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

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

See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all your 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")

Other things that need attention:

Your above posted system details show outdated plugin(s) with known security and stability risks that you should update.

  • Shockwave Flash 10.1 r82
  • Next Generation Java Plug-in 1.6.0_20 for Mozilla browsers

Update the Flash plugin to the latest version.

Update the Java plugin to the latest version.
