browser.sessionstore.resume_from_crash keeps resetting to False
I recently noticed that when I close Firefox via Task Manager's End Process method, it's no longer restoring my session when Firefox is opened again.
Apparently, browser.sessionstore.resume_from_crash has been set to False for some unknown reason, so I changed it back to True. However, it's always reset back "False" every time after I close Firefox normally or using End Process via Task Manager as it's not saving any changes made in the config.
What could be the problem?

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
- Don't make any changes on the Safe mode start window.

I was having this problem too and I just fixed it. I found a entry in user.js that was causing Firefox to reset the value back to false on restart.
To fix it I opened up my Firefox profile folder and opened the file user.js in notepad. After that I removed the line below and saved it.
user_pref("browser.sessionstore.resume_from_crash", false);

Yep, that will happen when you have a pref set thru the user.js file. When Firefox is opened the user.js is read last, and a setting made in user.js will overwrite a pref change made in about:config - IOW, a setting in user.js trumps a setting changed in about:config.
Hello,
It seems I don't have this user.js file in my profile folder, which I believe is in C:\Program Files\Mozilla Firefox\defaults\profile?
I also tried disabling all Add-Ons in Safe Mode, but it would still reset the value to False every time it's restarted. When I closed out Firefox properly, it would reload my tabs in the new session. However it still won't recover tabs from crashes or improper way to close Firefox like it used to.
I also have updated my Flash Plug-In and Adobe Reader plug-in as suggested.

The folder you want to open is described in this link.
[http://kb.mozillazine.org/Profile_folder_-_Firefox#Windows]
The files in C:\Program Files\Mozilla Firefox\defaults\profile are template files for a new profile.
Your profile folder is in this location:
- XP: C:\Documents and Settings\<user>\Application Data\Mozilla\Firefox\Profiles\<profile>\
- Vista/Windows 7: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\
- Windows: %AppData%\Mozilla\Firefox\Profiles\<profile>\
