It seems, for some reason, Firefox 4.0 beta 8 fails to load the CSS and JS of Google AdSense. The page loads only the text, but fails to display any layout, CSS or anything else.

The caches were clear. I opened the page for the first time since I got a new computer and it wouldn't display it properly. I cleared it afterwards anyway, but still no success.

I must admit, though, that I haven't checked if Google is doing User Agent sniffing and sending different content based on browser.

Reproducible: Always

Steps to Reproduce:
1. Log in with the Google Account that manages your AdSense.
2. Go to

Actual Results:  
On Firefox, if you're already logged in, you'll see a cyan/gray screen. On any other browser, it shows the AdSense dashboard.

Similar effects happen on other pages: On Account Creation, the text is displayed, but no layout information is loaded. The JS also seems to fail to load, with some parts displaying only "true" or "false".

Expected Results:  
Page rendered properly.

Again, I haven't checked if it isn't Google doing User Agent sniffing and sending broken/incompatible data.

I took a screenshot of a side-by-side comparison of the side in Firefox 4.0b8 and Safari. The starting URLs are the same, but it seems that, on Safari, additional information is loaded afterwards:

In this case, the URL was, already logged with an AdSense account.

Possibly due to Adblock Plus? (Seen in screenshot)

Could you see if the issue occurs with a new, empty profile:

Also, does it occur in the 3.6.13?

OH $(deity)s!

/me bangs head on the desk.

Yes, it was AdBlock. Once I whitelisted the Google domain, everything went fine.

Needs a "RESOLVED - REPORTERISSTUPID" option, though.

/me keeps banging head on the desk.
