Thunderbird is a popular email client used by many, but sometimes the font size can be a bit small and hard to read. This can be particularly frustrating for those with sight problems. Fortunately, there is a way to change the font size in Thunderbird and increase the size of everything, making it easier to see.
To begin, click on the three horizontal lines in the top right-hand corner of the screen. This will bring up a menu where you can click on “Options.” Scroll down to the bottom of the screen and move your mouse over “Config Editor” and left-click once.
You will now be taken to the inner workings of the system, so it is important to be careful with what you do and what you type in. If you are comfortable making changes to Thunderbird, click on “I accept the risk.” If you would rather get someone else to do this for you, simply click on the cross to come back out of it.
Once you have accepted the risk, type in “layout.css.devPixelsPerPx” in the search box. Double-click on “value” and change it to 1.25 to make everything 125% of the original size. You can adjust this value to your liking.
After making the change, click on “OK” and you will notice that everything has gotten larger. You can always go back and adjust the size by following the same steps.
It is important to note that depending on your eyesight, you may want to increase or decrease the size from the recommended starting point of 1.2 or 1.25. Play around with the size until you find what works best for you.
In conclusion, changing the font size in Thunderbird is a simple process that can greatly improve the user experience for those with sight problems. Remember to be careful when making changes to the inner workings of the system, and adjust the font size until it is comfortable for you.
