Frequently asked questions
Will my browser's popup blocker interfere?
Most browsers only trust one window.open() per user click. PageOpener opens the first tab synchronously on your Go click; the browser will usually then prompt you to allow popups for pageopener.com. Once allowed, the rest of the list opens cleanly in the background.
What is the difference between Pause and Stop?
Pause suspends the timer but remembers where you are in the list — pressing Go resumes from the next URL. Stop resets the cursor, so pressing Go starts again from the first URL.
How do intervals and jitter work?
The interval is the minimum number of seconds between two tab openings. Jitter adds a random extra delay of up to N seconds on top of the interval — useful when you don't want a perfectly rhythmic pattern of requests.
Why open in background tabs instead of new windows?
Background tabs are far less likely to be blocked than pop-up windows, keep your workspace tidy, and let you continue browsing without focus-stealing.
Can PageOpener stop the browser from switching to each new tab?
Whether a newly opened tab steals focus is controlled by the browser, not by JavaScript. Modern Chrome, Edge and Firefox default to opening background tabs and do not switch focus when the calling page uses window.open() with a target of _blank, which is what PageOpener does.
Are commas in URLs handled correctly?
Yes. PageOpener only splits input on whitespace and semicolons, so URLs containing commas (common in product pages) are preserved intact.
Does auto-close work on every site?
Browsers only allow a page to close a tab it opened. Since PageOpener opened the tab, it can close it after your configured delay. Some sites that navigate to a different origin may not close cleanly — that's a browser security restriction, not a bug.
Is PageOpener free?
Yes. PageOpener is free to use and is supported by advertising.
