Why do only some tabs open?

This is due to your browser's popup blocker. Tabs after the first may be blocked — click the popup-allow prompt in your address bar if that happens.

Can I enter URLs without a protocol?

Yes. Entering example.com will automatically prepend https:// before opening it.

Is the URL list I enter sent to a server?

No. It's handled directly by your browser's window.open API.

Nothing opens when I click?

Your browser popup blocker stopped them — allow popups for this site via the blocked icon in the address bar.

What if I omit http://?

The browser may treat it as a search term — paste complete URLs with https://.

URL list

⚠️ Depending on your browser's popup blocker, tabs after the first may be blocked. If so, click the popup-allow prompt in your address bar.

Example

Input

pdf.developk.kr
https://image-tools.developk.kr/
fuc.developk.kr

Output

https://pdf.developk.kr           → new tab
https://image-tools.developk.kr/  → new tab
https://fuc.developk.kr           → new tab
toast: "3 tab(s) opened"

Lines without a protocol get https:// prepended automatically, while blank lines and surrounding whitespace are ignored. Each of the three lines opens in its own new tab.

How bulk opening works

One URL per line — each opens in a new tab via window.open.

Element	Details
Input format	One URL per line — include `https://`
How they open	Browser window.open into new tabs — a popup blocker may stop them
Heads-up	If your browser blocks popups, allow them for this site first
