The real working solutions

If your goal is multi-engine OSINT search, these approaches actually work:

Option 1 — Browser extension (best)
An extension can open unlimited tabs because it has permission.

Option 2 — Bookmark folder
Put search engines as bookmarks and use “Open all bookmarks”.

Option 3 — OSINT dashboard + Ctrl-Click
Generate links and open several with Ctrl + click or middle mouse.

Option 4 — Local script (Python / Node)
A local script can open many browser tabs without popup blocking.
