I just got a brand spanking new Win 8 computer (intl English). The only things installed on it are Adobe Master's Collection, Steam, Office and Firefox. In addition I tried installing adblocker, because that's a must for me and if this problem is resolved by removing it I will have to switch to another browser.
Now, the problem is that FF is having problems loading pages with CSS. Occasionally, this results in a pages with nothing at all (except background color, it seems) or with just unformatted text. Most of the time this is fixed by doing a shift+reload, but not always. Some times it's just partially fixed and some elements don't load still.
I've tried disabling all extensions and plugins and I've also tried resetting FF. The problem always comes back. I've even tried resetting my hosts file.
Do you have any more ways of fixing it? I believe I've done everything in my power, except change browsers (which I really don't want to do unless it's my only option).
The only thing I haven't tried, which I'll try now, is unpin all my app tabs and see if that fixes anything. I'll update this if I can...
Pages affected: Facebook (some of the time), Couch Potato (installed on my server - never seen this on other computers or even other browsers on my computer, always), MyFitnessPal (occasionally), and some low-tech dating page I'm on.
So, it still happens with a new an clean profile without extensions?
In that case you may have security software (firewall, anti-virus) that block some content.
You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.
You can also try to use the Web Console (Web Developer > Web Console;Ctrl+Shift+K) to see if you can identify network related issues.
Yes, it happens with a clean profile. As for the security software, the first thing I did when I got the computer was removing the Symantec bloatware. The only security software now is Windows Defender. I guess I could try disabling the built-in windows software firewall...
The reload option isn't always an option. For one it's just irritating having to do it all the time for some pages and for a couple, like couch potato, it doesn't even work.
I'll have a look at the web console after work - thanks
Hmmm...no change when disabling the firewall, and nothing really bad in the web developer log.
This is what I'm getting from Facebook:

So, there's nothing that really screams out "this is going to fail!" as far as I can see...These logs are taken from pages that failed to load.
One more update - just to be sure, I ran the symantec removal tool in case there was something left behind the scenes (as there used to be) after uninstalling their software. Still no go.
I have the same problem here. I just have windows defender installed. I am attaching a screenshot of facebook. It happens for a lot of websites though. I hardly have any add-ons installed. I am currently running FF 16.0.2
I have tried the solution of pressing the Shift key and left clicking the reload button and it worked for me.
Wish I could help you, but it seems I may have "solved" my problem after a frentic fit I had last night. Ran the Symantec removal tool three times in a row, uninstalled FF, deleted all FF files (but kept my profile), reinstalled FF and copied back my profile. Now it seems to work - knock on wood.
My best bet would be that the deletion did more than the uninstall and that fixed it.
I'm having this same exact problem. Just got a new laptop with Windows 8 and firefox has been acting strange on it (CSS problem but also sites seem to be loading slowly in general). I did what you did Tiwas and uninstalled it and deleted all the firefox files on my computer, and it was running fine for a short period of time but the issues started popping up again. I think I'm going to have to switch to chrome for now, which sucks because I've been using firefox for years but I don't know what else to do. Maybe firefox just has some sort of compatibility issues with Windows 8 right now since it's so new, I can't think of any other explanation.
