How does the delay setting help?

Setting a 0.5-second or 1-second delay staggers the tab opening requests, allowing your browser to manage memory smoothly and preventing pop-up blocker triggers.

Do I need to include http:// or https:// for every URL?

No. Our tool automatically detects domain names (e.g. example.com) and prepends the standard https:// protocol if missing.

Is there a limit on how many URLs I can open?

There is no hard limit, but opening 20–30 URLs per batch is recommended to avoid excessive RAM usage on your device.
