This change consolidates duplicated logic between chrome_utils.js and
extension installer hooks, as well as between Python plugin tests:
JavaScript changes:
- Add getExtensionsDir() to centralize extension directory path calculation
- Add installExtensionWithCache() to handle extension install + cache workflow
- Add CLI commands for new utilities
- Refactor all 3 extension installers (ublock, istilldontcareaboutcookies,
twocaptcha) to use shared utilities, reducing each from ~115 lines to ~60
- Update chrome_launch hook to use getExtensionsDir()
Python test changes:
- Add chrome_test_helpers.py with shared Chrome session management utilities
- Refactor infiniscroll and modalcloser tests to use shared helpers
- setup_chrome_session(), cleanup_chrome(), get_test_env() now centralized
- Add chrome_session() context manager for automatic cleanup
Net result: ~208 lines of code removed while maintaining same functionality.
