axe-core: [extension] DevTools failed to load SourceMap: Could not load content for browser-polyfill.js.map

I uninstalled AdBlock and the problem disappear

@ivan-aksamentov F12 in the browser. then go to Settings. look for Sources, and disable the option: “Enable javascript source maps”

i tried to uninstall adblock and still doesn’t work

While waiting for a fix, for chrome, you can remove these warning from the console by deactivating Javascript source map in the dev tool as explained here

Thanks for everyone’s feedback on this issue, but having a lot of duplicate comments is not helpful at this time. We are aware of the problem, but it is only an issue with browsers being unable to load a sourcemap that is not bundled with the axe extension and does not affect the functionality of the extension.

Same Issue here in Brave Browser!!

Facing same error

This has worked for me -> https://stackoverflow.com/questions/35002087/disable-source-maps-in-chrome-devtools

same problem

I uninstalled Pop-up Blocker extension and every thing goes well

Thank you for reporting. We’ll look into it.

'Tho one year later… checking Selected context only under Console in the Dev. Tools Settings has solved it for me.

Small update: I randomly came across Chromium Bug 1052872 as it appears this was an issue introduced in Chrome. It appears they were previously not reporting sourcemap issues, but that combined with chrome not loading chrome-extension:// urls introduced the problem.

I can’t believe my eyes, people who posted “solution” like “disable the warning”, we are greatful!

15/08/2020 What i did. i remove unwanted Chrome extensions in url: chrome://extensions/. You may try it because it works for me. You can also identify which chrome extension is causing the error.

I solved it with pip install ipykernel --upgrade

I got the same issue with chrome !! but I did empty cache and hard reload to fix it

I just uninstalled AdBlock extension, and the problem is gone!

I removed Zotero chrome extension and the error gone. I think maybe some chrome extension crash with polyfill.js.map
