@thibaud57 I’ve opened a PR to resolve this issue: #1633 It fixes the problem where light_mode=False did not apply dark mode correctly. I fixed the issue where light_mode=False didn’t enable dark mode. Refactored BrowserConfig (renamed to performance_mode, added dark_mode), updated browser_manager.py to apply color_scheme='dark', added a dark mode test, verified with pytest, and cleaned up temporary test files. Looking forward to feedback and review.

Hi, the light_mode parameter is there to disable background processes, extensions, and other unnecessary features, making the browser more efficient. It's not for the dark and light modes of the browser

I will go ahead and close the issue, but please feel free to continue the conversation! :)
