Hello,

Somebody could tell me if I have any chance to adjust Inbox messages characters size whose source contains:

Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 7bit

Many times there is a separate font used for the cases you
mention, they are usually configurable under Options+Display then
fonts -- where that can allow you to choose fonts/encoding.

Also if you know how to get into the about:config option in
Tbird, and look for the
value of "layout.css.devPixelsPerPx", (I see it as a string value),
then changing that value from the default of -1 (or 1) to values like
1.1 or 1.2 should give about a 10 or 20% size increase across your
entire UI

I tried this "about.config" option as first attempt but for me it has no effect: default was -1.0 I changed to 1.0 and no effects on the UI.

I resolved my chars size issue just by disabling the option (I'm trying to translate from Italian to English):

Use fixed width characters for simple text messages

Now I have not to zoom anymore to read such small simple text messages in Thunderbird.
