Unity Player Crashing after Mac OSX 10.6.6 Update

Using either Safari 5.0.3 or Firefox 3.6.13 and connecting to EA sports online the unity player plug-in crashes immediately upon start-up and locks up either browser.

Has anyone else seen this?

My son tried to play jumpstart.com and unity is crashing there with 10.6.6 too with the "fatal content error" message. Then, tried to delete Unity cache and it locks safari with the same error (fatal content).

Update: I downloaded an updated Unity Plugin via the download page, and it is no longer crashing with OSX 10.6.6. I think the version that was crashing was listed as 2.6 and the new plugin is version 3.1. This updated plugin no longer seems to crash (at least when my son tries to play Jumpstart.com).
