Create, save, run, stop scripts that open tabs in the background without stealing focus. **Tab Runner** helps you open multiple URLs in the background without interrupting your current tab. It is built for repeatable browsing workflows where you want to save a script once and run it again later with the same timing and URL rules. ## What Tab Runner does - Create and save multiple scripts - Open links in the background with a configurable delay - Use either a manual URL list or a template-based URL loop - Generate URLs with `{year}` or `{i}` placeholders - Preview generated URLs before running - Reorder saved scripts with drag and drop - Run or stop a script directly from the extension - Reuse the same tab or rotate URLs across new tabs - Control how many URLs open in each tab - Enable optional mobile emulation - Apply optional header profiles - Keep the same workflow across Firefox, Chrome, and Edge ## Script types ### Template Loop Use a URL template with placeholders such as `{year}` or `{i}`, then define: - Start - End - Step This is useful for repeated searches, archive browsing, and structured URL patterns. ### URL List Paste one URL per line to create a fixed queue of pages to open. This is useful for research tasks, review queues, and saved groups of links. ## Tab reuse options Each script can control how tabs are reused: - `0` = always reuse the same extension-opened tab - `1` = open each URL in its own new tab - `2` or higher = reuse each tab for that many URLs, then open a new tab This makes it possible to keep tab counts under control while still working through large URL sets. ## Typical use cases - Repeating searches across multiple years - Opening research pages in the background - Running saved batches of links - Automating structured browsing tasks - Testing pages with mobile emulation enabled ## Quick start 1. Open the extension 2. Create a new script 3. Choose **Template Loop** or **URL List** 4. Set the delay and tab reuse behavior 5. Save the script 6. Click **Play** to run it 7. Click **Stop** to end the run at any time ## Notes Tab Runner opens URLs that **you define** and stores your saved scripts locally in the browser for reuse.
