grr.
something's changed on the backend of facebook because suddenly my firefox gets pissed off trying to load certain pages and hangs. Mostly my wall or other people's walls. When i clear out the cookies and cached sessions &c of my browser, it still happens, but when i try to load any fb page out of google chrome, i have no issues.
this leads me to believe it's a cookie filter setting, as in one or some of the cookies that i was able to block from fb before (such as ad cookies) is now confusing fb and is causing a script loop.
it's annoying because i don't feel like deleting all of my exceptions to build them up again nor do i feel like pouring over them to find ones that might be related to fb, but i don't want to keep on using google chrome for it because the cookie filtering in google chrome is less flexible than firefox, and opening an incognito window specifically for facebook is silly.
ah well.
