Open the practice page, run Test this page, and confirm the live monitor catches browser activity.
Welcome
Your first win is one supported page that proves it works.
Session Activity Helper is browser-only. Start by testing the exact web app that keeps interrupting you, then save repeat workflows once you know the page behaves well.
It cannot move the operating-system cursor, prevent device sleep, or override site, school, workplace, browser, device-management, or administrator session rules.
Pin the extension.
Keep Session Activity Helper visible in the Chrome toolbar so the status is easy to check.
Open the real page that times out.
Use a normal website tab, not Chrome settings, the Web Store, or another extension page.
Run Test this page.
Confirm the helper can inject, then start a visible session and watch last pulse.
When Pro makes sense
Upgrade after the first page proves useful.
Free is for one saved site and manual testing. Pro is for repeat workflows where saved profiles, advanced recipes, longer run windows, and diagnostics are worth more than restarting sessions by hand.
Compare Free and Pro- You use the same CRM, dashboard, training portal, or admin tool every week.
- You want saved site profiles instead of rebuilding settings.
- You need longer run windows, advanced recipes, or support report export.
