Power BI Blog styling doesn't load in Firefox desktop or mobile

[DominicBisset]

The styles fail to load when I visit https://powerbi.microsoft.com/en-gb/blog in Firefox (tested in Desktop version 135.0, Android version 135.0). The website falls back to the web browser's default styling, rendering the dropdown menu as raw nested Unordered Lists and images get rendered at their native resolutions (whatever that may be). It's not unusable, but it is unpleasant.

The website does work in Edge (tested in Desktop Version 133). And for contrast, the Fabric blog https://blog.fabric.microsoft.com/en-gb/blog/ does render correctly.

(This is probably the wrong place for this but I couldn't find anywhere better. Sorry)

Hi  @DominicBisset ,

Based on the above information, this issue is complex which may need to collect log files for further troubleshooting. Since community support engineers don't have that access, I would suggest opening a Support Ticket. If you are a Power BI Pro or Fabric licensee, you can create a support ticket for free and a dedicated Microsoft engineer will come to solve the problem for you. 
It would be great if you continue to share in this issue to help others with similar problems after you know the root cause or solution.

A few notes: - This was working in Firefox without issue up until a month or so ago. - If I access via this link, the styling loads without issue: https://powerbi.microsoft.com/en-us/blog/?cdn=disable

Or maybe it just suddenly got fixed. Regular link (https://powerbi.microsoft.com/en-us/blog/) works for me now too.

That's a great spot. The cdn=disable version of the url does indeed get the site working again. It seems the sites not fixed in general. I was able to visit the vanilla version of the link on my phone and it was broken, then accessed the cdn=disable variant successfully and now the vanilla version of the link works properly. All that implies that url parameter must be setting some long term state behind the scenes. And indeed if I clear cookies and session storage for the site then lo and behold it's back to the broken state again. Visit cdn=disable again and things work again.
