The Console in two places: “Panel” “Drawer” – Console features reference  |  Chrome DevTools  |  Chrome for Developers

Posted by jpluimers on 2026/02/17

I always forget nomenclature, so in my mind the terms for the two consoles in the Chrome web development tools (official nomenclature: Chrome DevTools) are these:

  1. The primary console in a separate tab of the DevTools
  2. The secondary console at the bottom lf all tabs in the DevTools

The posts caused some uproar, and in order for myself to understand what is going on and what questions should be asked to PostNL, I wrote this blog post.

In any case: always remove parcel labels before disposing of the parcels, then destroy the labels. This has always been good privacy practice and will stay that way forever.

 

Regrettably, Tweakers.net blocks both the Wayback Machine and Archive Today, which makes their information ephemeral. Therefore I archived some of the Tweakers.net information in the gist [Wayback/Archive] “E-mailadres van ontvanger kan in PostNL barcode staan” archived from https://gathering.tweakers.net/forum/list_messages/2327530/0 · GitHub
