Remove Unused Javascript for better performance

[ad_1]

Hey there,

I’m working to improve the performance of a WordPress website. I installed WP Optimize and it’s working good, but on mobile it’s still 55, but on desktop it’s 90 , from the Source -> Coverage I can check the large JS file, they are, for example :

[https://theme/wp-content/cache/wpo-minify/1667994835/assets/wpo-minify-header-c069994d.min.css])
[https://connect.facebook.net/signals/config/840878223409940?v=2.9.89&r=stable])

[https://theme/wp-content/cache/wpo-minify/1667994835/assets/wpo-minify-footer-296e12dd.min.js])

How can I remove these files ?
