Your System Details looks very light/empty. Can you start by giving us the troubleshooting information from the Firefox installation that's having problems. This is an essential step in troubleshooting.

• Click the Firefox button at the top left, then click the Help menu and select Troubleshooting Information from the sub-menu. If you don't have a Firefox button, click the Help menu at the top and select Troubleshooting Information from the menu.

Now, a new tab containing your troubleshooting information should open.

• At the top of the page, you should see a button that says "Copy text to clipboard". Click it.
• Now, go back to your forum post and click inside the reply box. Press Ctrl+V to paste all the information you copied into the forum post.

The first bit of information (shift + left-click the reload button) solved the problem. I am sending the information requested in the bottom where it states "Your System Details looks very light/empty....."
