I greet all those who have entered)
I study the extensions in Chrome, all the tasks related to the extensions are reduced to something to enter on a previously known page, copy the data, and transfer wherever
the most FUNNY is that all the examples I’ve come across, such as writing an extension in 10 minutes, are reduced to styling beautiful icons and drop-down HTML content when you click on the extension icon, i.e. there is no autonomous work
tell me whether it is possible to write an extension (are there any words for googling or code that will scare) so that when you open the browser (not the page), you can run whatever JS code is generally primitive whatever, like go to whatever site, count the number of characters in HTML, and send this value wherever you are, well, there is a file or GET / POST Request
This is the most adequate that I found, but again, you need to press something
