For me it’s lack of convenient hotkeys and keyboard-based navigation. Used Vimperator on FF until they killed it. Now using qutebrowser, which uses qtwebengine, wbich uses outdated chromium. Sad story.

Use std::string_view to sort of get the safety of std::string without copying the contents (just in general make sure the original c string won’t get freed or overwritten, which won’t happen to argv in your case).

Or just std::string and yolo, the overhead of copying the contents is negligible in your use case.
