Answers
- Ctrl+Shift+N (Chrome, Edge); Command+Shift+N (Safari 15+ on macOS with privacy features; Firefox also uses Ctrl+Shift+P for private window in Windows/Linux and Command+Shift+P on macOS)

- Run a few tests: check other devices, run a speed test, try a different site, reset your modem/router, and flush DNS (ipconfig /flushdns on Windows; sudo dscacheutil -flushcache on macOS)
- .zip (common) or .rar; on Windows you can use tar, 7z, or PowerShell’s Expand-Archive to extract a .zip; for .tar.gz you’d use tar -xzf
- In PowerShell: Get-ChildItem -Force or dir -Force to show hidden/system files; in Command Prompt: dir /A:H
