Close Firefox main windows without closing private window will clear all your session tabs
I'm not sure whether it happens at current version of Firefox or already happened previously, but if you close your Firefox main window without closing your Private window first, all your session tabs will be lost when we launch Firefox again. Is there any way to recover my previous tabs?
You can check if you can reopen closed windows:
- History -> Recently Closed Windows/Tabs"
Use one of these to close Firefox if you are currently doing that by clicking the close X on the Firefox Title bar, especially if you have multiple windows open to prevent losing tabs in unnoticed windows.
- "3-bar" menu button -> Exit (Power button)
- Windows: File -> Exit
- Mac: Firefox -> Quit Firefox
- Linux: File -> Quit
