User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b8) Gecko/20100101 Firefox/4.0b8 Build Identifier: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b8) Gecko/20100101 Firefox/4.0b8 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 http://www.google.com/adsense 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: http://i.imgur.com/6Qfa4.png In this case, the URL was https://www.google.com/adsense/v3/app, 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: http://support.mozilla.com/en-US/kb/Basic%20Troubleshooting#w_make-a-new-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.
