• Click on the three stacked lines icon present at the top right of the browser window.
• Then select the question-mark icon at the bottom of the drop-down menu.
• Now click on the 'Troubleshooting information' present in the slide-out menu.
• You have to click on the 'Reset Firefox' button.
• Then choose the 'Reset Firefox' in the confirmation pop-up window.
