Firefox isn't accessing some CSS unless manually told to
Any website I visit, whether for the first time or the ten thousandth, has about a 50/50 chance of rendering without any CSS. Sometimes a site will load fine, but other times it loads as a white page with a long vertical list of links, images and text, all without formatting.
I have searched and searched for solutions to this problem. I disabled all add-ons, ran Firefox in safe mode, reset Firefox, cleared the cache, cleared cookies, made sure the settings allow websites to specify their own colors and fonts. Sometimes doing these things will buy me a little peace; usually not. It's hard to say because each website has such a random chance to mess up.
Normally, I can fix the problem by hitting refresh 1-5 times. Eventually, Firefox retrieves the CSS and everything works. I recently discovered Shift + Ctrl + R for an instant fix. However, I have no way of knowing if that fixed the problem for good for that website, since the next time I visit it, it could be fine or it could mess up again.
Amazingly, I don't think Facebook has ever had this problem for me. Netflix, Gmail, random internet forums, however, all have. There's really no pattern that I can see. The only reason I even know (suspect) it's a problem with the CSS is from all the research into people with similar problems.
Currently, I have NO add-ons running.

Just got it to happen again: website loaded without CSS, opened the console, refreshed, still no CSS. The first GET line trying to access a CSS file was [undefined]; clicked it and found request headers but no response headers again.
I'm about ready to switch to a different browser (even though I REALLY don't want to - I love Firefox) if I can't figure this out.
That can be caused by a corrupted cache.
Are you using any cleanup programs that affect the Firefox cache (about:cache)?
You can try to remove the entire cache folder in the location shown on the about:cache page.
