I have FF v51.0.1 32 bit for Win 10 Home 64bit. Usually I have about 5-10 browser tabs open simultaneously while surfing. Lately I find that FF closes earlier tabs on its own, without asking, and without my closing them myself. I must right-click and select "Undo Close Tab" to restore these tabs. In FF Options, I have unchecked "Warn me when closing multiple tabs" Any ideas what I need to do to keep this from happening?

Wellllllllp, turns out my galpal installed an Add-on, "Unload all tabs" which closes tabs after they're open a preset time. Problem solved!

Separate Security Issue: Update your Flash Player Note: Windows users should download the active_x for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).

Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the active_x.

Flash Player Version: 24.0.0.194

Have you seen any pattern? What are the addresses of the closed tabs? How long are those tabs open when they are closed? Are you using any ad-blockers?

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?
