Chrome is weird or where did someone else's code come from?

PHP

In general, I am doing one PHP analyzer in Notepad++ via FTP.
I edit, save, update, look at the HTML code that came out.
And then <head>this came up:

<script>(function(){var b=window,f="chrome",g="wtsrt_",k="tbsd_",l="tbnd_",m="start",n="_wtsrt",p="_tbnd",q="CSI/";(function(){function h(a){this.t={};this.tick=function(a,d,c){this.t[a]=[void 0!=c?c:(new Date).getTime(),d];if(void 0==c)try{b.console.timeStamp(q+a)}catch(e){}};this.tick(m,null,a)}var a;b.performance&&(a=b.performance.timing);var r=a?new h(a.responseStart):new h;b.mobilespeed_jstiming={Timer:h,load:r};if(a){var d=a.navigationStart,e=a.responseStart;0<d&&e>=d&&(b.mobilespeed_jstiming.srt=e-d)}if(a){var c=b.mobilespeed_jstiming.load;0<d&&e>=d&&(c.tick(n,void 0,d),c.tick(g,n,e),c.tick(k,g))}try{a=
null,b[f]&&b[f].csi&&(a=Math.floor(b[f].csi().pageT),c&&0<d&&(c.tick(p,void 0,b[f].csi().startE),c.tick(l,p,d))),null==a&&b.gtbExternal&&(a=b.gtbExternal.pageT()),null==a&&b.external&&(a=b.external.pageT,c&&0<d&&(c.tick(p,void 0,b.external.startE),c.tick(l,p,d))),a&&(b.mobilespeed_jstiming.pt=a)}catch(t){}})();})();
</script>

</body>And suddenly this appeared before :

</script>

On subsequent checks, this was not found. Who has experienced this?

I also noticed such a script, the "Traffic Saving" plugin is to blame for everything
