Research direction
Reproduce the error at the linked etherscan.io URL, then inspect content_scripts/mode_visual.js around line 138 and trace the Selection handling that calls getRangeAt. Confirm the behavior when no selection range exists, and consider the issue done when that scenario no longer produces an uncaught IndexSizeError.
