RE: Clear-Site-Data header support

Edge has not begun implementation of Clear-Site-Data; the feature will not be present in the upcoming fall release.

John, understood, and thank you! I will make a note to check back on the site regularly to see if CSD moves into "Under Consideration", etc.

If anyone can comment for Microsoft Edge, it would be appreciated.

Hi John, good to hear from you and thanks - I knew those weren't the right places and appreciate you sharing the canonical source!

Are you aware of any plans for Webkit to support Clear-Site-Data in the future?

We typically don’t comment on future plans. But the WebKit Status page will say “Under Consideration,” “In Development,“ “Supported In Preview,” and “Supported” accordingly. In rare cases, an engineer might have started development without bumping the feature’s status yet.

   Regards, John

Hello WebAppSec Team,

Hoping to clarify browser support for Clear-Site-Data header.  As of this writing here's what I believe to be true.

- support: as of Chrome 61
- source:<>

- support: as of Firefox 63 (shipping in October 2018)
- source: Dan Veditz' email on this distro on July 20, 2018 (thx Dan!)

- support: "No public signals"; didn't find anything definitive from the Safari team
- sources:<> and<>

WebKit's official feature status is not found on<> or<>, but here:<> 😉

WebKit does not support Clear-Site-Data as of now.

   Regards, John

- support: "Public support", though I didn't come across anything definitive from the Edge team
- sources:<> and<>

Would particularly appreciate any info from the Safari and Edge folks on the list here.

Much appreciated,
Caleb Queern
