Browsers open in pairs CONCURRENCY_BROWSER

[galaczi]

I found an old issue: https://github.com/thomasdondorf/puppeteer-cluster/issues/341

I am experiencing the same.

    concurrency: Cluster.CONCURRENCY_BROWSER,
    maxConcurrency: 1,

This opens 2 browser windows. One is empty, the other one is used. If I bump it up to 2, then I have 4 windows, 2 empty. Is this normal?

it is normal.

Yup unless you force PPt to use current tab but it's normal behave for Puppeteer itself, as you launch browser with 1st tab and then open a new one by default
