I have the following firefox extension. I want to get cookies from the browser. But when I click “All” in the extension, the console.log(await (browser.cookies.getAll({})) only print an array of zero length. I tried to compare with the following package, but I can not see what is the difference that causes the problem. How can I find out what causes the problem?
