Hi there. You can scrap the page with many methods, you can go with the extension one. Create an extension that will be automatized, with some inputs such as what you want to be scrapped. Same thing with the script relying on python language. You can automatize the whole process (including the run the browser and closing it), and both of those approaches have some advantages and disadvantages. If you can tell me what exactly you plan to scrape so I can tell you with a precision, what method is better to build.
Also, when do you plan to start the project and when is the deadline?
Anyway,s feel free to hit me up so we can talk more about this. I am very responsive. All the best
