When FF restarts after a crash, why does it not restore my previous session?

Firefox crashed twice today (on the same URL), and each time it restarted, it did not honor my option to "restore the previous session". Each time it restarted with one window, I checked my options, and the "restore previous session" option was still set. The happened last week also. FF 32.0, Windows 7 Professional 32-bit. Thanks.

Hi Barry, can you use History > Restore Previous Session?

I think you need to fix this setting:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the search box above the list, type or paste sess and pause while the list is filtered

(3) Double-click browser.sessionstore.resume_from_crash to switch it from false to true

You might also want to reset or at least increase these values, but based on our earlier thread, perhaps these would make your session history less stable:

browser.sessionstore.max_windows_undo is currently zero

browser.sessionstore.max_tabs_undo is currently zero

Since you have Advanced SystemCare, you may find that some Firefox edits are reverted. You may need to turn off the settings protections feature(s) of ASC.

I have toggled browser.sessionstore.resume_from_crash from false to true, and I will see what happens after the next crash. I did not increase the other two parameters from 0.

I again disabled the ASC Surfing Protection Addon. I had disabled it on August 17, but somehow it got re-enabled.
