title: How to modify an installed extension on Chrome?
body: <p>An extension I used a lot changed developers and the new versions, even though they have some bugfixes, have annoying scammy advertisements. I managed to remove them by downloading the .CRX file, extracting it, editing the code (simple HTML) and then adding it to the browser using "Load unpacked extension". Problem is, every time I launched Chrome, there was an annoying pop-up telling me that developer mode was on and that I had to disable it. I tried the .BAT file that was supposed to edit some .DLL and stop the pop-up, but it didn't work. What are my alternatives? How can I edit an extension that I've installed through the store?</p>
  
  <p>EDIT: I found the assets on my PC, problem is, every time I remove the pictures, Chrome automatically downloads them again. How can I disable that?</p>
