As a result I have to select the whole message and set size 12.
My lines often use paragraph marks rather than let text wrap around.
Also left and right arrow to move cursor don't work.
Also pages seem to jump in to the compose text box for reply without any action on my part.
I am using a p-585y tablet, android 6.0.1. Firefox 53.0.2 - many tabs lined up but not loaded.
(While composing this the same thing has happened, this time all the text is large but the line starting with 'My' is much smaller.)
