It's hard to understand what you're willing me to do. Keywords like const are ECMA-262 (2016) features, and I don't see any reason to use them right now.
Also, your code looks broken (unescaped /, unfinished ', etc.) but it might be because you need to use code sections when pasting code.
If instead you think that some websites have changed and so don't work properly anymore, please give me a link and the source code of the website around the checkbox.
