Chrome Dev Summit 2021

Chrome Dev Summit 2021 is a big event in the browser industry at this time of the year. It is a two-week-long event, with lots of workshops, learning lounges, and live discussions. It is also the time and place where the Chrome team makes their important announcements. Here are the highlights of this edition:

  • Compat 2021 initiative is going strong
  • New types of apps are coming to the web (note: see the update about the web version of Photoshop in last week's issue)
  • A pledge to ensure privacy (note: we'll see what the future brings here, as the track record is not sterling)
  • Improve Core Web Vitals
  • Enable new platform features
  • Provide courses to help you learn web technology (note: I think this is a great initiative, and they have some awesome people working on these courses)

This summary is just scratching the surface therefore I invite you to find more info in the article below.

Browser news


The Microsoft Edge team published their November update. The highlight, in my opinion, is the announcement that the stable version of Edge is now available for Linux users. There are more achievements claimed in the announcement, but I let you check them yourselves.


Firefox 94 is now rolling out to all users. The updates are focused on privacy, with Site Isolation (first announced back in May) and the official Firefox Multi-Account Containers extension with Mozilla VPN integration. This extension separates cookies by container so that you can use the web with multiple identities or accounts at the same time.

The team claims improved performance on multiple platforms:

  • use of Apple's low power mode on macOS
  • background updates for Windows users (even when the program is closed)
  • better power consumption and WebGL performance on Linux
  • improved JavaScript speed and memory usage

Let's not forget the Colorways: six themes for your browser to "suit (or lift) your every mood". Their words, not mine... Also, available for a limited time only.

Polypane 7

I was about to publish this issue when I got the notification that Polypane has just released version 7. This update runs on the beta version of Chromium 96. The updates are too many to list them all, but here are some highlights:

  • There is a new color picker tool that works everywhere on your screen
  • You can edit pseudo-elements and pseudo-classes directly in your Elements panel
  • The Web Vitals overlay now shows CrUX data when available
  • Integrated support for, allowing you to screenshot and annotate parts of your page and export them to an external tool like Jira, Asana, Slack, or even email.
  • Horizontal overflow detection
  • The new Polypane Share features allow you to create links and share them with your team, either as a URL or a QR code
  • New debug tools and simulators, including ones for glaucoma, macular degeneration, and cataracts.

If this is of interest to you, be sure to check the release notes.
