In reply to Stephen Herman.

Thats a very good question. Ultimately, the answer depends on your apatite for risk and the nature of the data that you handle. If the data on your desktop is particularly sensitive, maybe its time to switch to another browser until a patch is available. However, the real danger was before the zero day was identified and published when there was no protection whatsoever.
This won't be the last zero day. Keeping systems fully patched is very important but I think most important is to protect your most important systems and to monitor their use so you can swiftly identify malicious access. There are many ways that attackers could get inside your network, zero days are only one of these, but by being able to spot attackers when they get in, you can protect your most important assets and take action to remediate the breach.
