If you’re like most people, Firefox was always open in the background. But if you’ve ever closed a tab in Firefox and reopened it later, you may have noticed that the tab’s icon was different. If it wasn’t before, it likely was after Mozilla released a fix for a bug that caused tabs to close unexpectedly when you opened them again. To keep your tabs open and inactive when you reopen them, follow these steps:

  1. Open Firefox and click on the three lines in the top left corner of the window. This will show your current tabs list.
  2. Click on one of your previously closed tabs and select “Open in new window.” This will open a new window with Firefox installed and all of your currently open tabs active.
  3. Close the old window by clicking on its closing symbol or pressing Esc key.

If you’re tired of losing your place when you close or restart Firefox, there’s a simple remedy: Turn on “Restore previous session” in Options, and you’ll get all your previously open tabs back the next time you restart. Here’s how to set it up.

First, open Firefox. In the upper-right corner of any window, click the hamburger button (three horizontal lines). In the menu that appears, select “Options.” (On a Mac, click “Preferences.”)

In the Options tab, select “General” from the sidebar, then locate the “Startup” section. Place a checkmark beside “Restore previous session” to turn the feature on.

After that, close the Options tab. The next time you restart Firefox, your tabs will be reloaded exactly as you left them before.

Note that this setting will not work if you have configured Firefox to always start in Private Browsing mode. That setting forces Firefox to always forget your browsing sessions every time you close it.

Happy browsing!
