• (2019-11-07) Brian Gregory: Great. But how about showing HTTP/3 now that Chrome supports it?
• (2019-03-21) Jakob Hirsch: gives deprecation warning in recent chrome versions because it's using loadTimes. Nice ext though.
• (2018-10-31) yu liu: why i cannot see the red color, even when i open google and youtube? I have enable QUIC in my chrome. it always shows the blue color with http2 enabled. but i didn't find quic session

• (2017-09-07) Jovien Chia: Very nice and handy extension. Highly recommended to check whether your connection to a particular server is on which type of protocol.

• (2016-03-25) Michał Kwiatek: blue icon on dark theme doesn't look good
• (2016-03-11) Александр Шишенко: Great tool, but latest update was not cool. A tiny icon in address bar is better (and less clutter-y) than a huge button.

• (2016-01-23) Oleksandr Fradynskyi: Thank you!
• (2015-12-02) Dead J. Dona: put icon back to address bar!!!!!!!!

• (2015-10-21) Hanxue Lee: Simply works
• (2015-10-18) Yasin inat: Thank you.

Latest issues

• (2020-07-23, v:1.0.0) William Feely: Add indicator for HTTP/3 QUIC
  Just tested on quic.nginx.org after enabling QUIC h3-27 in the command line, but the extension is not indicating any accelerated protocol. Perhaps, since SPDY is dead use red for HTTP/3?
• (2019-07-15, v:1.0.0) Nicholas: Chrome load times
  Hi Chrome loadTimes() will be deprecated. It already started to show up some warnings. It would be good to fix it. https://www.chromestatus.com/features/5637885046816768 Thanks
• (2019-03-22, v:1.0.0) Dark Mode color-scheme
  The Blue used to indicate HTTP/2 is poorly contrasted when in Dark Mode. Perhaps automatically switch the color in Dark Mode to a yellow/green, or make the color selectable - either by explicitly setting it or selecting from a small list of options
• (2019-01-27, v:1.0.0) Thomas Copper: HTTP/2 and SPDY indicator has to be updated
  Chrome 71 doesn't use chrome://net-internals/ any more, now it uses chrome://net-export, so this extension no longer compatible with latest chrome and has to be updated.
• (2018-12-14, v:1.0.0) Tomas Rakusan: net-internals has been removed
  Chrome 71 no longer has net-internals. I think that this might be the reason why this extension no longer distinguishes between h2 and quick.
