I’ve put together a quick repo to demonstrate the problem: https://github.com/Stuk/webpack-sourcemaps-firefox
And here’s a gif of the issue in action:
I’ve checked Uglify, and Firefox has no issues there. I’ve tried the different config options for
cheap-source-map– does not work
cheap-module-source-map– does not work
source-map– does not work
So seems like eval is file, but an external sourcemap for multiple files does not.
Any thoughts about what’s going on?
I’ve also filed an issue on Bugzilla, in case this is a FF devtools issue: https://bugzilla.mozilla.org/show_bug.cgi?id=1177329
