I used to get excited when I'd get a new video game. Now I'm super excited for the new vacuum we bought. AMA.

I guess there are some folks upset about browser efforts to move the web to https. This post was a great round-up of the complaints and counter-arguments:
Nice explanation of CORS: https://frontendian.co/cors
Interesting read on the current state of cross-origin attacks and mitigations in browsers: https://www.arturjanc.com/cross-origin-infoleaks.pdf
@nolan Did the pinafore "compose tweet" button go away on desktop firefox? I can't seem to find it now...
This is seriously impressive! Pure html and css paintings.

@nolan How is the server configured for pinafore? Is it something I would be able to replicate?
One oddity I noticed is that the pinafore SW script does not seem to do 304 revalidation in firefox. I think maybe the headers are not quite configured right.
@nolan FWIW, I'm fairly certain there is a bug in firefox somewhere causing this. See: https://bugzilla.mozilla.org/show_bug.cgi?id=1456840
@nolan Do you sometimes push changes to pinafore.social without bumping the version number? Trying to determine if all the "update available" dialogs I see are from legit changes or firefox making a mistake.
Fetch API default credentials are now "same-origin" in today's Firefox Nightly 61 
. Ships in June.
Thanks to Anne van Kesteren for spec, Dominic Farolino for WPT tests, and Matt Gaunt for prodding. https://toot.cafe/media/x8xOJ6PyUp4xk2Cpzd0
Apparently #firefox is the only browser that does not set a referer header on <meta http-equiv="refresh">.
14 year old bug that someone reported recently again as an interop issue:
https://bugzilla.mozilla.org/show_bug.cgi?id=266554
Made a test here:
I guess maybe pinafore does not show opengraph cards yet? Is that correct @nolan?
Simplified my blog by moving it off of octopress and onto default jekyll. The jekyll minima theme seems much more readable than what I had before.
I wonder if the opengraph data will show up correctly here...

This is a great post by Dave Rupert on the various "laws" we run into in tech: https://daverupert.com/2018/04/eponymous-laws-of-tech/
Firefox 61 will include Request.destination support thanks to Catalin Badea's work in https://bugzilla.mozilla.org/show_bug.cgi?id=1402892
Also thanks to Yoav Weiss for writing the WPT tests for this feature.
