What is the repository `playwright-browsers` ?
Hi, I'm trying to build firefox on my own in order to attempt to fix a network bug in page reloads. I've built firefox on my own following Mozilla docs and I'm trying to understand how playwright builds browsers. It seems like this script is intended to be run internally and depends on a playwright-browsers repo that is not public available: https://github.com/microsoft/playwright/blob/main/browser_patches/roll_from_upstream.sh
Am I getting this right?
This thread is trying to answer question "Is the script intended to be run internally and does it depend on a 'playwright-browsers' repository that is not publicly available?"

Answer
Sure, let's dive into how Playwright manages browser dependencies and how you can configure it to download browsers from custom locations.
Managing Browser Dependencies
Playwright keeps track of the packages that need browsers and cleans them up as you update to newer versions. You can opt-in for this mode by adding the following line to your .bashrc:
export PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsersThis tells Playwright to manage and track browser dependencies based on the packages you're using.
Downloading Browsers from Custom Locations
By default, Playwright downloads browsers from Microsoft's CDN. But if your company maintains an internal artifact repository to host browser binaries, you can configure Playwright to download from your custom location. Just set the PLAYWRIGHT_DOWNLOAD_HOST environment variable:
export PLAYWRIGHT_DOWNLOAD_HOST=https://ray.run/your-custom-locationIf your company uses an internal proxy that blocks direct access to public resources, you can configure Playwright to download browsers via a proxy server. Set the HTTPS_PROXY environment variable:
export HTTPS_PROXY=https://ray.run/your-proxy-serverThat's it! Now you know how to manage browser dependencies and configure Playwright to download browsers from custom locations. For more tips and tricks, check out our blog.
