Firefox keeps changing from 3.6 to 15


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.
