It's been happening ever since July 31st. Any time I start or re-start Firefox, or when it crashes and I have to open it back up, it completely reverts to my Firefox session from July 31st, and not the current session. An attempt to delete from my Firefox folder lead me to this message - "Cannot delete sessionstore.js: The file or directory is corrupted and unreadable." Is there anything I can do to get rid of this problem (read: any solution that isn't drastic). Many, many thanks in advance...

Create a new profile as a test to check if your current profile is causing the problems.
See Creating a profile:

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem

You can do a disk check with the chkdsk.exe program. If you run the chkdsk.exe program from a cmd.exe Command window then you can read the response from the chkdsk.exe program. Open a cmd.exe window: Start > Run: cmd.exe <press Enter> At the command prompt (>) type or Copy&Paste: chkdsk.exe /f /r <press Enter> (put a space before /f and /r) If you get something like: Would you like to schedule this volume to be checked the next time the system restarts? y/n then answer the question with "Y" and close all programs and reboot the computer.
