I am 74 years old. I have been using ThunderBird for my email management for years. I like the program except for one thing. The displayed font size on the program desktop is too small.

I want, need, would like to be able to change the font size on the displayed screen. I am having eye strain reading this print size

I created a screen shot of my ThunderBird Desktop which is saved a as file: ThunderBird Eesktop screen shot 001.rft 12/7/2020 9:03AM Rich Test Format 10,602KB. This program will not allow me to attach this screen shot. The font size displayed on my monitor is to small. I need it to be larger... thus easier for me to read and use. Thank you

You can only upload an image if it is an image file eg: jpeg Rich Text Format is not an image file, it's a text document.

Note: reducing the screen resolution of your computer/monitor may help with general use of computer.

To increase the general overall font size in Thunderbird, please do the following: If using version 68*:

  • Menu app icon (icon has 3 lines) > Options > Options > Advanced > 'General' tab
  • click on 'Config Editor' button to open 'about:config'

It will say be careful :)

If using version 78*:

  • Menu app icon (icon has 3 lines) > Options
  • in Left pane select 'General'
  • Scroll down to the very bottom
  • click on 'Config Editor' button to open 'about:config'

It will say be careful :)

Now you can see the 'about:config' window

  • In search type: pixels
  • Look for this line: layout.css.devPixelsPerPx
  • Double left click on that line to open the 'Enter string Value' box so you can edit the Value.

The default value will be a negative number: -1.0

  • Enter a new positive number eg: 1.25 or 1.5 or 2.0 or 2.2
  • click on OK

the effect is immediate, so you can modify that number until it looks ok for you.

I've included two images as a guide, first is version 68* and second is version 78*

If images seem small, in this forum, click on the images and they will increase in size.
