Answer 1

@Brian Wiltshire:
I’m not sure if this is the source of your problem, but I and others found this fixed the problem of the “WebProcess” pop-up windows.
Safari 5.1 and “WebProcess”: PROBLEM SOLVED
The culprit is “Little Snitch”
I am running OS 10.6.8 (Lion-ready). Yesterday, I installed the Safari updater from 5.0.5 to 5.1 . . . and am experiencing repeated and annoying pop-up windows for "WebProcessing."
I found the culprit to be the third-party utility "Little Snitch" — which monitors outgoing internet connections. (http://www.obdev.at/products/littlesnitch/index.html).
I solved the problem by upgrading (FREE) Little Snitch v2.0.x to v2.4 (for Snow Leopard and Lion).
PROBLEM SOLVED.
