2. Opera

1. Click on the Opera button in the top left corner and choose Settings.
   
2. Scroll all the way down and click on Advanced.
3. In the Privacy and security section click on Site Settings.
   
4. Select JavaScript and make sure that the Allowed (recommended) option is enabled.
   

If you’re not familiar with Opera, you should know that it comes with a built-in ad-block, so it won’t show you any ads. By disabling the ads and its scripts, your webpages will load faster.

Opera also has tracking protection, ability to detect malware, and for an extra layer of security, there’s a free VPN available with unlimited bandwidth. If you already haven’t, be sure to give Opera a try.
