not all thumbnails loading on slow sites
Here is a slow loading site: http://www.elbisemodelleri.com/hm-2011-yaz-bikini-mayo-plaj-koleksiyonu.html
If I have either NoScript or Adblock Plus enabled, then some of the thumbnails will not show. (This happens on many slow sites, not just this one).
If it was just one extension, I would blame that extension. But only enabling one of the two results in the same behaviour. This started happening when I upgraded from an older Firefox version (sorry I do not remember the version) to Firefox 11. Then I upgraded to 12, still the same issue.

Are all the network.http prefs on the about:config page have the default value (i.e. are not bold, user set)?

Doesn't it clearly indicate that NoScript or Adblock simply blocked the elements you see as not loaded? If so it's more like filtering rules issue rather than a slow network or Firefox issue. I recommend narrowing it down to either Adblock or Noscript and proceed from there.
If there is no problems with both (or all) extensions enabled then you need to check the settings in the extensions to see if content is blocked.
A bit more context: I administer a website for a photography club. The cms is rather slow. Since my upgrade to firefox 11 I noticed that on pages with many thumbnails, some random thumbnails do not load. I first thought it was the cms, since I upgraded that too around the same time. It is only when the same behaviour happened on other sites (a silly example of such a site where it happens every time is in my first post above) that I understood it was a problem with Firefox 11. I then upgraded to version 12, but it still happens. There are no rules in Adblock or Noscript that would block these images on my own site. Besides, the thumbnails that refuse to load are random, hitting reload a few times makes them appear. I have absolutely no idea how extensions "communicate" with Firefox, but it seems to me that somewhere one side is "giving up" on slow loading graphics. And since this behaviour is new after upgrading to version 11, maybe it is Firefox that is not "waiting long enough" ... ? Again, yes, normally the extension is the logical culprit. But here two extensions, both used on a large scale, each individually have the same effect. Could it not be Firefox then ?

Thank you! Turning off pipelining (a "tuning" I did ages ago) solved my issues.
You're welcome.
Yes, HTTP pipelining can cause issues with images not loaded properly as stated in the MozillaZine Knowledge Base article.
That happens with servers that do not properly support pipelining.
