I use Outlook and started using Thunderbird. When I compose messages, I use Calibri 11 (medium). In Outlook, at 100% zoom the size of the text is easy to read (at least for me). In Thunderbird (zoom reset), the size of the text is smaller (see attached picture). I can zoom Thunderbird three times to make the text about the same as I see in Outlook, but the zoom does not save. I cannot find an option for saving Zoom settings in messages nor could I find an add on. I found Zoom for the entire program add on, but not for text size in the messages. It may exist but I cannot locate one as of yet. I also checked Tools / Options / Composition to see if there was a way to make the text display bigger. I can change my default font used in emails but no zoom / display setting. Is there an option to maybe save the zoom and/or display the text bigger when composing a message? Thank you. Shawn
