Thunderbird 78.5.1 (32-bit) Interface, icons and text size

more options

Hi everybody,

I was just w riting to ask as I can only seem to increase the font of the e-mail written text, but really the interface size is absolutely ridiculously small and is there any way I can enlarge this (without reducing the resolution of my monitor which is not really a solutuion)

Not everyone has the best eyesight for this kind of thng and I find thunderbird the best mail and calander client but at least on windows or in browser-mail I can CTRL+ to zoom in and read, it's at the stage where I might have to use the windows magnifying tool just to see t hings like "inbox" "spam" and my list of emails' titles.

Please tell me there exists an option to make all this larger like interface size, I mean come on almost every modern software has an option bar slider to increase these things

Cheers

Thunderbird does have a preference setting to change pixel ratio.

  • Menu app icon > Options > General
  • Scroll down to the very bottom
  • click on 'Config Editor' button to open 'about:config'

It will say be careful :)

  • 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 -1.0

  • Enter a new 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. Please note the default is a negative number, but you need to remove it entirely and retype, so not creating a negative number. Image below as guide.

Hello all I found this solution verry helpful thought a suggestion (if anyone from mozilla ever reads this is to just add a bloody slider-bar)

hope it helps anyone in the future as it's really quite cryptic way of doing such a basic function.

Just click the thumbs up arrow.

But really this is not the location for discussion on the user interface. There is a special list run by the developers of user interface discussions. Perhaps you could put your views on a needed interface forward there. I have wasted years trying to get them to listen.

On MacOS instead of "Menu app icon > Options > General" you must visit Preferences under the Thunderbird menu or hit Command-comma. If you have Thunderbird 68 The 'Config Editor' button is not under General but it is in the Advanced area at the bottom. Thunderbird 78 has it under General.

I followed the istructions exactly changed it to -01.25 and it made no difference to the font size in the IN Box - I then closed and reopened Thunderbird - What now please.

I am disappointed - I want to be able to use thunderbird without spectacles.

it seems a far too complicated process for an IT dummy like me - beware here be dragons - I had to get past!

re :I followed the istructions exactly changed it to -01.25 You followed the instructions very well, but failed to follow them when entering the value. The default is a negative number -0.1

The instructions said to change it to eg: 1.25 which is a positive number and the decimal point is after the number 1. The instructions did not say to use a negative number : -01.25 Nor did they say to put a 0 before the number 1.

I suggest you have another go and this time clear all the current entered value and retype to use this 1.25 or 1.5

Excellent - thank you vewry much - I still wish it were easier - but I will see how I get along with 1.25 - initially it seems a bit big - maybe next I will try 1.125
