Description: when adding the email notification settings under configuration > notifications > send email notifications I enter all the information and when I click save it switches send email notifications back to disabled. If I click to enable it, it takes me to the screen to enter my information again that has been blanked out. Same thing happens if I click on "test smtp settings". This doesn't happen in FireFox 62.0.2 so I'm able to work in there.
Workaround: Use FireFox 62.0.2
