An issue in Panic Button affecting Tab Groups

Firefox 138, which was released this week, introduces Tab Groups, a long-overdue feature for organizing your browser tabs. For those not familiar with it, there's an article on the Mozilla Blog with details.

Panic Button currently doesn't handle tab groups when restoring your browser windows, if the Panic Button action is set to Hide and Replace. The tab groups are lost upon restore -- but the tabs themselves are intact.

I'm investigating how this can be fixed. Until then, consider changing the Panic Button action to Minimize All Windows or Minimize Current Window. These will keep your tab groups intact while offering some level of safety if a nosy coworker, roommate or spouse tries to look over your shoulder.
