Do you employ any filtering of web content? Ad-blockers, IE8's
InPrivate Filtering, anti-malware that include URL blocking, using a
'hosts' file to block ad or malicious sites, etc. If you filter out
content then you can also filter out scripts that define objects that
another script expects to have been defined. For example, if you filter
out Google's crap (like their analytics and other tracking sites) and
because many sites use Google's services for tracking, you end up
blocking a script that defines objects that another script expects to be
defined. Blocking ads and other content can result in script errors.
