Why pop-up blockers affect bulk URL tools
Modern browsers protect users from unwanted windows. That protection is useful, but it means bulk URL tools work best with clear user permission and conservative pacing.
Quick answer
If only one tab opens, your browser probably blocked the rest. Allow pop-ups for this site, keep the batch size low, and add a delay between batches.
Use smaller batches
Opening one to three URLs at a time is more reliable than launching a large list.
Keep a delay
A pause between batches gives browsers time to process each tab.
Watch browser memory
Large pages, videos, and dashboards consume memory quickly when many tabs open.
Repeat with leftovers
Copy unopened URLs and run a second smaller batch if needed.
Open multiple URLs in controlled batches
A multiple URL opener lets you paste a list of links, normalize missing protocols, and open them in small batches with a delay. This reduces pop-up blocking and helps you review many pages more safely.
