We install certutil and pk12util if necessary:

sudo apt install libnss3-tools

On Linux, Chromium uses the NSS Shared DB. Check if you have the ~/.pki/nssdb directory:

ls $HOME/.pki/nssdb

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
