Follow these steps only if URL contains "salesforce.com/setup/layout/flsedit.jsp?id=00e"

Step 1 : Run the below code 

    /* Copy from this line */
    flsStorageProfile = "SALESFORCE#COPY#FLS#HOST:"+window.location.hostname+"#ProfileId:";
    
    var query = window.location;
    var profId = (query+'').split("salesforce.com/")[1].split("/e?")[0];
    
    flsStorageProfile += profId;
    
    var table = document.getElementsByTagName("input");
    for (var i = 0; i < table.length; i++) {
        if(table[i].type == "checkbox" && table[i].checked) {
            
            var field = table[i].name;
            var acc = table[i].title;
            
            if(!flsStorageProfile.includes("<"+field+">=R") && acc == "Read Access") {
                flsStorageProfile += "<"+field+">=R;";
            } else {
                flsStorageProfile += "<"+field+">=V;";
            }
            
        }
    }
    
    console.log(flsStorageProfile);
    /* Copy until this line */

Step 2: the above will print some output, copy that and paste in the below code: 

    /*Copy from this line*/
    var flsStorageProfile = '*****PASTE HERE THE OUTPUT FROM STEP 1******';

    var inputFields = document.getElementsByTagName("input");
    for (var i = 0; i < inputFields.length; i++) {
        if(inputFields[i].type == "checkbox") {
            
            var field = inputFields[i].name;
            var acc = inputFields[i].title;
            
            if(flsStorageProfile.includes("<"+field+">=R") && acc == 'Read Access') {
                inputFields[i].checked = true;
                inputFields[i].style.outline = '2px solid #3330e5';					
            } else if(flsStorageProfile.includes("<"+field+">=V") && acc == 'Edit Access'){
                inputFields[i].checked = true;
                inputFields[i].style.outline = '2px solid #3330e5';
            } else {
                inputFields[i].checked = false;
            }				
        }
    }
    /*Copy until this line*/
