Firefox changes my security settings.
When I log in to Firefox I have to go to the Options tab and check the "Remember logins for sites" under Security every time. I have tried refreshing Firefox, but this didn't help. The only changes I have made recently to my add-ons, etc. is that I have upgraded to version 45.0.2. The problem is occurring on both my home desktop computer and my laptop computer.

hi, other users of trend micro security software have reported similar issues - the trend micro password manager that might be automatically installed as a separate application on your system might responsible for that behaviour. please uninstall it through your system control panel in case you're not using it.

Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.
