I recently (meaning 10 minutes ago) solved an issue with my browsers.
I tried loading Youtube about an hour ago. It connected quickly to the server, showed me a blank page with the correct title (YouTube - <accountname>'s YouTube>, Firefox 3.5 showed it was busy loading but nothing happened.
After a few more tries, I switched to Internet Explorer 8, which I recently updated to, no go there either; now, I didn't install IE8 when it came out since FF3.5 is my primary browser.
I Googled around a bit, a number of similar complaints on various boards (usually not a bad sign). When I tried reading some of the search results, the same bug stung me, it gave me a blank page and infinite loading. Turning add-ons for FF3.5 on and off didn't do anything, nor did networked safe-mode.
I remembered IE8 and FF3.5 have about 0 in common so it had to be either connection-related or some 3rd party application not doing something it should or doing something it shouldn't. The first thing that came to mind was java, maybe with the updates, I missed a new java.
I surfed to the download site for Java. Turns out I had version 6.13 and there was a 6.14 available. I downloaded, installed, checked youtube and almost precisely after I typed youtube.com and released my enter key the page had loaded. Problem solved!
Thought I'd stick this here for all to read, in case someone has a similar problem
