Google Chrome doesn’t have a single-click method of refreshing multiple tabs simultaneously; however, you do have some workaround options for accomplishing this. Chrome can save opened tabs and restore refreshed versions of them when you restart the browser. This method only works for a single window, but forcing a crash expands this capability to multiple windows. You can also bookmark multiple pages to reopen them all at once. This option offers you the ability to reload them on subsequent Chrome sessions, even if the tabs aren’t already opened. Tips Warnings Writer Bio
