Dashboard font suddenly changed

link to small font screen
link to normal font screen

please start with double-checking and resetting all browser zooms – particularly the ones in your effected login page.

Thank you! I couldn’t work out how to do that, but I switched to Google Chrome and now it’s OK. Very strange, I’ve no idea how I managed to alter Firefox without even knowing ???

Ctrl+0 should restore default size in Firefox.

Thanks, I did Ctrl+0 and it made it right in Firefox.
