For some reason my default PDF reader keeps being changed to MS Office instead of just opening them in the browser as I directed. I keep having to change the setting in Firefox every couple of weeks (general > applications > PDF). What's causing this?

My system default is Office 365. Would the system settings change the browser setting, though?
