Small example at https://test-sourcemap-local.glitch.me/ , the red div uses sourcemapped styles. This one points to `file:///Applications/MAMP/htdocs/sourcemaps.css.map` which happens to be where I have my local copy of the sourcemap for this project. So on my machine, devtools show correct sourcemap info on this website, while you should not see anything unless you create it yourself at the same path with the content from https://test-sourcemap-local.glitch.me/sourcemaps.css.map The correct variant is at https://test-sourcemap-regular.glitch.me/ FWIW it seems that Chrome also resolves my local stylesheet, and Safari doesn't.
