It proved to be unmaintainable due to the following reasons:
- determining upstream branch for the technology preview was a manual
and tedious process
- once determined, actual Safari Technology Preview occasionally
diverted from the branch
This patch:
- rolls Firefox to v1269 which is now a firefox-stable build.
- introduces a new channel, `firefox-beta`, for our internal needs.
Fixes#6817
This is a small change to show that ffmpeg is a supported browser parameter
value in the script usage. Although, the whole file should probably be
refactored now to something more generic like roll_download.js since ffmpeg
is just reusing the logic and isn't a browser.
We now commit protocol.ts files during the roll.
New utils/roll_browser.js helps with that.
This makes our installation very shallow:
- build installer;
- download browsers.
