I cannot enable HTTPS MODE. It is greyed out on my settings so I can't change it. Will you check my account for irregularities?

Hi
Have you considered updating to the most recent version of Firefox?
You appear to using a version which is very close to being three years old.
Note that in such an old version you would likely have to do this directly via the about:config page as this hasn't been added to the user the settings page, but I do not know if there are unresolved issues with HTTPS-Only so use at your own risk if you do not want to update.
- about:config => dom.security.https_only_mode
