A simple Google Chrome extension that will hide users on a webpage

Maybe I can do this for you if you agree to buy some cheap computer peripherals I need, which will worth $10 in total. I said maybe because if the job turns out to be complicated due to the design of the web page in question, then I'll have to ask for more. Some people go crazy when we do this but hours we spent has a price... And jobs posted here are usually impossible tasks, I'll not be surprised if the web page in question has a quantum superposition feature for the listed elements to make what you want impossible to do. Plus I don't want to deal with extensions for this job, I can do a quick solution which will work by pasting a script into the javascript console of your browser. You can autoload it using tampermonkey extension if you want. Hit me from chat if you want to try this, but I'm saying it again, from my experience so far, there'll be a lot of obstacles that will take my time and thus cause it to cost more. Probably people know that is also why your project has very few bids.
