Please advise. Thanks.

EDIT LOOKS LIKE ALICE HAS FOUND THE KEY, with the post above.
I do note some of the crash reports show no extensions, but maybe that is a fault with the crash reporting process as you say it runs in safe mode. (The first one you posted is available now and an example with only the default theme shown.)
Your crash signature is rather rare, you may be the only person generating that signature on Firefox 18 at present. Some signatures show thousands or even hundreds of thousands of crashes per week. It is likely to be a problem on your own machine, and you have taken the initial steps in ruling out malware.
We do know it runs in safe mode, so rather than considering malware further, or what the exact cause may be lets just go ahead and try and get it working again retaining as muchdata as possible,
Whilst doing this you may as well do a clean install involving deletion of the program files.
You will need to carefully read all of this ('''Unless a simple reset works''')

# I do not like using this particular step. (There are often moreconservative methods of solving problems) but if it may well work and if so saves you a lot of trouble.''' (Note you may loose some preferences ). Ensure you have any extensions home sites etc bookmarked, all extensions will be removed and all open tabs & tab groups.'''
##Use Reset option from safe mode or troubleshooting.
## try Firefox is it fixed now ? if so you just need to get the extensions back. No need to continue with the remaining steps.
# If problems persist <br />Using safe mode or an alternative browser download a suitable fresh copy of Firefox from

# Backup the profile and copy it some where safe (such as the desktop) outside firefox program or profile paths.
# Remove the firefox program folder either manually or using the control panel and reinstall the new copy.
#Now copy back some of the old profile files to the new profile in order to restore bookmarks and passwords etc.
Good luck, please post back with how you get on.
