Browser Extension Safety — Кроки навчання

1. Tab Overload

   It's a busy Wednesday. Alice has been deep in a data migration project, and her browser has become a graveyard of open tabs - 47 at last count. Finding anything takes longer than the actual work.

2. A Colleague's Tip

   A new email arrives from Marcus Webb, a colleague on the analytics team.

3. Visiting the Web Store

   The extension sounds useful. Alice clicks the link to check it out on the Chrome Web Store.

4. A Quick Install

   The Chrome Web Store listing looks polished - a 4.6-star rating, clean screenshots, and exactly the tab management features Alice needs. The blue 'Add to Chrome' button is right there.

5. Permission Request

   Chrome displays a permissions dialog for TabMaster Pro. The extension requests several permissions to function.

6. Quick Check

   Before moving on, a quick question about what just happened.

9. Opening the Portal

   Alice needs to log into the Security Operations Portal to review the investigation findings.
