  • (2021-02-20) Lőrinc Ambrózy: It would be nice if it could show versions above http/2. Because CF currently supports v3 too.
  • (2020-06-30) Michael G.: Simple and very useful, also to check if everything is alright with the own config.
  • (2020-04-05) Lorin Halpert: For some reason it is not picking up HTTP/2 even though trace clearly shows "http=http/2". Accessing remote via IPv6.
  • (2018-10-05) Alan Hale III: Is this still being maintained? HTTP/2 and IPv6 indicators are not lighting up for sites that are known to use HTTP/2 and IPv6.
  • (2017-04-05) Kari Linder: It's excellent and I love it
  • (2016-10-20) István ifj. Dankaházi: Please prepare Apple Safari!
  • (2016-06-24) Joshua Pack: Works good
  • (2016-02-09) Greg Johnson: The plugin is currently broken. If the site is using CloudFlare and the resource you are viewing is cached, the icon does not show up. If you are on a site that is using CloudFlare and you are viewing a resource that IS NOT cached, the icon does show up.
  • (2015-08-24) Jonathon Runge: Great plug in. Nice to know who uses CloudFlare not to mention SPDY and IPv6

  • (2013-03-29) I do not see omnibar icon anymore. Is this still working as intended?
  • (2013-02-22) g. coleman: more bling than an Oakland sideshow!
  • (2012-08-06) Noah McIlraith: It would be awesome if it were possible to configure the extension to only show the CloudFlare icon on CloudFlare-powered websites (show no icon on sites that aren't, instead of a gray icon).
  • (2012-05-19) This app is however crashing on the latest version of Dev Channel.
  • (2012-05-18) Joseph Page: Helpful. To optimize bandwith, is it possible to use only HEAD request ?
  • (2012-02-23) Joshua Motta: CloudFlare is awesome

    It would be nice to see the Extension in the new Chromium Edge Store
  • (2019-11-06, v:0.11.0) Mark Krieger: QUIC support
    Hi there I really like the extension, but sites that use QUIC don't show HTTP2 as active. Will you add support for QUIC (and display it as well) or is this extension EOL? Thanks
  • (2019-07-13, v:0.11.0) Val Vesa: great extension

  • (2016-10-06, v:0.9.1) Ryan Knight: Re-brand
    Hi - Cloudflare recently did a re-brand, changing the F to lowercase and updating the logo. Any chance you can refresh?
  • (2016-08-11, v:0.8.2) R N: Railgun compression value missing
    When I access any website that uses Railgun, extension shows compression ratio as NaN%.

  • (2016-06-21, v:0.8.2) Emil Rasmussen: Seems to have stopped working
    Hi This plugin seems to have stopped working - I'm on Chrome Version 50. Best regards Emil
  • (2015-09-02, v:0.7.0) Christopher Kalafarski: Lots of false negatives
    This extensions seems to function very sporadically. The icon will show up correctly, and then the page is refreshed and it goes away. It's a handy tool when it works, but it doesn't work well enough to rely on.
  • (2015-08-20, v:0.7.0) Bulut Korkmaz: Screenshot
    You are using a screenshot from Safari, and it is not showing features of this extension.
