Firefox - all open tabs gone, again!

Hi, yet again, I've opened Firefox to find just one tab, a Mozilla ad in this case; the 40 or so tabs I had open are gone. I had prepped for a day's work ahead and had opened the tabs I needed for research and work, ready to start in the morning. I don't know what's causing it; I do know that this most often happens when I've shut down Firefox, then go to Thunderbird for a last check of emails, and click on a link in an email which opens Firefox.

Is this a bug? Does Firefox just not like being opened via an email link? Is it a problem if a Firefox private window has been left open inadvertently, even though Firefox was properly shut? Or is it just Firefox updates that cause this problem? It's been happening for a while now, and is really frustrating and costly, workwise. Yes, I do have restore previous session ticked. I've shared the data report below - at the time of this post, not at the time of opening Firefox. Any help would be really appreciated, especially if it's simply explained :) Thank you

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

Thanks. I'll try to remember to do this alternative closing method, although it's not exactly instinctive - the X to close is what I've used for ever. I rarely have more than one window open anyway, all new tabs are opened in a new tab in the same window. The only extra window I'd ever have open is a private window. The problem is more about Firefox opening directly from a Thunderbird email link - that's when Firefox can open with just one tab. And judging by how many people have searched this problem, it looks as if I'm not alone in this! Thanks again.
