Custom Sourcemaps wót wartmanm

Custom Sourcemaps adds a devtools panel in which you can define custom source maps for scripts that don’t provide them.

Permissions

• webRequest, webRequestBlocking, <all_urls>: Used to modify headers on script requests.
• storage, unlimitedStorage: Used to retain source map settings across browsing sessions, and store uploaded source maps.

Limitations and known issues

• Only scripts with “src” attributes are supported, not inline scripts or eval()ed strings. Non-http(s) sources will also not work due to bug 1475832.
• When first opening the panel, all scripts on the page are shown, even if they were blocked by Tracking Protection, NoScript or others.
• Scripts substituted by Decentraleyes may not be shown or might not have source mapping applied.
• Uploaded source maps don’t always work correctly. While it’s less convenient, they can be added as file:// URLs instead.
• Scripts with pre-existing source maps are not identified.
• Source mapping is only done after you open the dev tools for a page.
