# test_verify.sh - Verifies extension and exits (doesn't wait forever)
#
# This script is a test version of test_start_extension.sh that:
# - Starts Firefox with the extension
# - Verifies extension loaded without errors
# - EXITS after verification (instead of waiting forever)
#
# Used for automated tests in CI/Docker.
