@jasvir Technically, significant portions of Firefox are built with JS, and the original firefox addons were scripting against those internal API's.

This was changed to WebExtensions API awhile ago: https://t.co/83k6tDUpRp

@code_punkt @playwrightweb I guess this is the way browsers work! If you try to save-as-PDF without playwright, is it instant?

(I'll leave this here for my future self.)

Node.js is leaking memory when using Promise.race with a long-living promise. And sadly, this is actually by design.

@kettanaito you can launch your server in global setup, but it'll be just there - in a separate process from the test processes. You'll then need to setup some cross-process communication between your tests and your server

[Andrey Lushnikov @aslushnikov]

@sedrak_ I've been doing this for the last 11 months as well! Great stuff!

Using Cypress, but wanna try Playwright?

Here's a new handy REPL for converting Cypress tests to Playwright.

1. Paste your existing Cypress test on the left-hand panel.

2. On the right, it displays the equivalent @playwrightweb test.

Handy.
