How to close or get rid of blank page which consumes unused memory

Hey, when I tried your example code in headless:false mode it opens a blank page which is idle and stays until the task are completed. And if the task goes on for a long time this blank page is observed to use around 600 Mb. How can I get rid of that blank page since it consumes some memory ?

Here is your example code which reproduces this issue

const { Cluster } = require('../dist');

(async () => {
    // Create a cluster with 2 workers
    const cluster = await Cluster.launch({
  puppeteerOptions: {
            headless: false,
            },
        concurrency: Cluster.CONCURRENCY_CONTEXT,
        maxConcurrency: 2,
    });

    // Define a task (in this case: screenshot of page)
    await cluster.task(async ({ page, data: url }) => {
        await page.goto(url);

        const path = url.replace(/[^a-zA-Z]/g, '_') + '.png';
        await page.screenshot({ path });
        console.log(`Screenshot of ${url} saved: ${path}`);
    });

    // Add some pages to queue
    cluster.queue('https://www.google.com');
    cluster.queue('https://www.wikipedia.org');
    cluster.queue('https://github.com/');

    // Shutdown after everything is done
    await cluster.idle();
    await cluster.close();
})();

Please don’t do this because then puppeteer-extra will not work properly! They only apply hooks on new pages not existing ones.

Yes, good point. This part could be improved by using the first (already open) page instead of opening another one…
