It happened again and I followed midimagics instructions by deleting my private data and refreshing and that fixed it. I took a screeny so Dani and everyone can see what Firefox does sometimes to DaniWeb.
I have seen the same happen to many sites including Yahoo and GMail, and it happened on both browsers IE6 and Firefox,
The situation in which this happened was the page was taking too long to load (mostly due to a slow net connection) and suddenly in between the connection drops or we manually stop the page from loading.
I am guessing the browser managed to download all the text / html components and was downloading the images,css etc when the connection was interrupted, so it ended up displaying the text/html components alone, I arrived at this conclusion cause in "lynx" which is a text based browser, daniweb looks pretty similar to what is shown in the screenshot.
Yes, I wanted to show people what it looks like and see if anyone else experiences it. I looked at my error console and it says that there was parsing problems in the daniweb css so the value was dropped.
