I'm having the following problem in my web application and it only occurs in the Mozilla Firefox browser: "Content-Security-Policy: Page settings blocked loading of a blob resource: https://sitename (“frame-src”).”

I am using the SheetJs library to export a .xls file in javascript, when generating the file using the writeFile method, the mentioned error occurs.

I've used a private browser, removed all extensions, cleared cache, etc.
