A small script that clicks all the buttons on the Facebook ad preferences screen to hide all ads and remove all interests. Maybe it neutralizes ads on FB and keeps me from being in a filter bubble?

clearAdPrefsOnFb.js

//Instruction: 

// 1. go here https://www.facebook.com/ads/preferences/?entry_product=ad_settings_screen
// 2. open dev console
// 3. paste code below and execute expandAll()
// 4. repeat for all categories that aren't shown simulaneously

function expandAll(){
    var intr = setInterval(function(){
        var btns = document.getElementsByClassName('_45yq'); //the class name of the expand buttons
        for(var i=0;i<btns.length;i++){
            btns[i].click();
        }
        if(btns.length == 0){
            clearInterval(intr);
            clickAllNo();
            return;
        }
        console.log('expanding...')
    },200);
}
function clickAllNo(){
    var buttons = document.getElementsByClassName('_2b2p') //the class name of the buttons that you click to hide stuff
    for(var i = 0;i<buttons.length;i++){
        var b = buttons[i];
        var bType = b.getAttribute('data-tooltip-content');
        if(bType.indexOf('See')>0) continue; //needs to be fine tuned to other languages
        if(bType.indexOf('Add')>0) continue;
        b.click();    
    }
    console.log('all done!')
}
expandAll();
