Some users of Internet Archive Downloader extension for Firefox encounter "Cross-Origin Request Blocked" error. The "allow CORS" function had been integrated into the extension, but it does not always work for all Firefox releases on all platforms. The reason is unknown. So come the CORS Patch extension. Or other third party CORS extensions will also be help.
- Grab the latest package (.xpi) in the releases page.
- Drop the package from file manager to Extensions page on your browser.
Alternatively, install automatically from Browsers repositories:
All Optional permissions must be granted.
No any works needed.
