Firefox doesn’t prompt me to save the password when I log in. Does the log in page prevent this from happening? (for security?)
If so, this makes it more difficult to use passwords that are too long and difficult to remember- for security. 
Does it need to be this way?
We didn’t do anything to prevent passwords from being saved, no. Actually passwords save fine on Google Chrome, so it could be because how Firefox handles password saving differently.
I just did a quick test on Firefox, and it looks like it’s indeed not saving. Do you mind me moving this thread to the “Bug” section so we can track it?
