XLS Download of embeded Power BI reports does not work in Firefox.

In chrome and edge this works.

step1:

step2:

step3:

The error is the FF Console. Download is not started

I tries all kind of CSP settings in the Top HTML file, all without success.

Again, Edge and Chrome are working fine.

Hi @JohanDamen ,

Please try:

Close csp
Enter about:config in the address bar to go to the configuration page.
Search for security.csp.enable and change true to false.

Turn off mixed content detection
Enter about:config in the address bar to go to the configuration page.
Search for security.mixed_content.block_active_content and change true to false.

Best Regards,

Hi, thanks for the quick feedback.
I've applied both settings as described. Restarted Firefox. All without success.

The following error message appears in the console of Firefox:
Content Security Policy: The page’s settings blocked the loading of a resource at blob:https://app.powerbi.com/df6093d2-ccb7-4e61-afcc-5cd2cc05430f (“default-src”).
