While the prospect of "patched" software may seem appealing, it carries significant risks that users should consider:
This is the natural conclusion of a cycle that has played out for decades:
Many student exploits rely on forcing administrative extensions into a crashed state. Recent Google updates have made it significantly harder to force-quit or manipulate enterprise-forced extensions via the browser's internal task manager or memory allocation tricks. 3. DNS and URL Filtering Updates
