How do I activate JavaScript in my browser?

Internet Explorer

Select the “Extras” option from the menu on the bar at the top. Select “Internet options”. Click on the “Security” tab. Click on “Adjust level”. Scroll down to the section with the heading “Scripting”. Select “Activate” from the two “Scripting” options and click on “OK”.

Mozilla Firefox

Click on the “Menu” option on the bar at the top, then select “Add-ons”. In the “Add-ons Manager” window, select “Plug-ins”. Click on the Java (TM) platform plug-in (Windows) or the Java applet plug-in (Mac OS X) to select it. Check that the option “Check if it should be activated” or “Always activate” is selected. In older versions of Firefox, click on the “Activate” button instead. (If the Deactivate button is displayed, Java is already activated)

Chrome

Open the main menu (on the right next to the address bar). Select the “Settings” option. Click on “Display advanced settings” and then on “Content settings ...” under “Data privacy”. Under “JavaScript”, select the first option (“... allow for all websites”). Click on “Finish” and update the browser (F5 key).
