several times a day, Firefox goes from version 15 to 3.6. I started Firefox this morning and it was 15 I closed Firefox. I reopened Firefox and it then told me that there was an update to 3.6?? I opened Firefox and it was 3.6. I closed it and came back later and it was v15 again. Then happens regulary and I am constantly being told that there are updated here and there. I only have 15 installed. No version 3.6 in Add/Removed programs etc. This is crazy stuff. Yesterday, I completely removed all traces of Firefox, I also deleted all Firefox folders. I reinstalled 15. It worked for the day. I opened it this morning and 3.6 was back andasking for updates. Please fix! Others in my office have similar issues it seems.
