Description

Steps to Reproduce

  1. Open Firefox on iOS.
  2. Open several tabs in tab tray.
  3. Go to device settings and set the date forward with a week and a day and also change the time one hour later.
  4. Return to Firefox tab tray and tap on the trashcan.
  5. Select close older tabs-->one week ago.

Expected Result All the tabs are closed and the tab tray is empty (except for a homepage tab).

Actual Result One (or sometimes more) of the tabs is NOT closed, so in the tab tray you will see that tab and the homepage tab.

A couple of times we noticed that the oldest tab is the one that doesn’t close, but we don’t have a clear pattern.
