Any chance to adjust the font size EVERYWHERE in this ridiciously shrinked layout of Thunderbird 68.1.0? Theme Font & Size Changer is to no avail anymore.

Sorry, but what the heck happened? You removed css, so layout.css.devPixelsPerPx is gone, too.

On computer: Note: If you are using a screen resolution that is large eg: lots of pixels per inch/cm then everything on desktop will appear smaller.

I use 1920 x 1080 and everything looks ok.


There is a way to enlarge fonts size in Folder Pane, Message List etc You need to do the following. Make Hidden files and folder visible:

In Thunderbird:

  • Help > Troubleshooting Information
  • click on 'Open folder' button

a new window opens showing the contents of your Profile folder.

  • Close Thunderbird now - this is important.
  • Create new folder and call it chrome note the spelling - use a lower case 'c' It should be in the same place as the 'Mail' folder.
  • open Notepad
  • Copy everything - all the text between lines below and paste it into the Notepad document.

/*
 
* Do not remove the @namespace line -- it's required for correct functioning
 */

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); 

/*
*Make all the default font sizes eg:14 px:
*/

   * { font-size: 14px !important; } 

If this proves to be too small you can edit the 14px to say 16px etc

  • Save the document as filename userChrome.css in the 'chrome' folder. Note the spelling all lower case except for the 'C'.

Start Thunderbird.

I'd say there's no need for any drama. ;-)

Toad Hall already provided a perfect solution; meanwhile layout.css.devPixelsPerPx can also be reached again.

Enjoy your Thunderbird! Love & Hugs, Max

I agree. I'm pretty sure that if my name was Karl Camp, no one would be talking about "any one could do it" and no need for any drama. Think about it! So no drama here--and I really appreciate the hug!--just the frustration expressed by many other users that this extra work needs to be done at all in midst of a heavy workload. I'm a retired university professor, with plenty of brain power, but this is NOT my area of expertise and I have little access to technical help. So Max, if I add some screen shots of what got complicated for me, can you help?

I'm running OS 10.14.6 and Thunderbird 68.4.1. Here's a screen shot of what I get trying to follow the very first instruction. I don't see an "open folder" button. I opened a number of folders to try to find my way to the right spot with no luck.

KateCamp I agree please spread some honey on T-bird with Theme Font and Size changer. That'd be sweet!

Dear Kate (a "Karl" would be also embraced!) - and others,

please see this very helpful instruction below from 2017. I am on a 4k monitor, setting my layout.css.devPixelsPerPx to 2.4:


"Post Posted November 17th, 2017, 11:45 pm I figured it out. Maybe this can be stickied or something somewhere. Maybe it is but it seems like a fairly common thing that people want to adjust. Especially with high res/ppi display settings. Maybe it'll save some people an hour or so of searching + experimenting.

At first I typed about:config in the urlbar and searched for layout.css.devPixelsPerPx. This will scale the entire Firefox UI. I changed the value to 2.3 (or whatever you want. Changes are immediate) using default font sizes. That may be ok for some but I wanted to go a step further.

The font options for each bar are:

.tabbrowser-tab .tab-text {font-size: 10pt !important;}

  1. urlbar {font-size: 10pt !important;}
  2. personal-bookmarks .bookmark-item > .toolbarbutton-text {font-size: 10pt !important;}

for tabs, urlbar and bookmarks toolbar. This made all the font sizes the same. You can use px (pixels) instead of pt (points) and also add weight options, etc, within the brackets. Combine UI scaling + font settings to your hearts content."

Thanks ... "changes are immediate" when you ....? Hit enter? I really appreciate the effort. Many of us just don't speak the language so every instruction is followed blindly with little idea of what chaos might result and even less idea of how to undo the potential damage. :)

xoxo, Kate/Karl

On OS X, click Show in Finder instead of Open Folder (Windows) or Open Directory (Linux).

The method for adjusting the preference has already been given in this thread, but the OS X instructions are: open Preferences/Advanced/General/Config. editor, or click the 3-bar icon at upper right, Options/Options/Advanced/General/Config. editor, right-click the preference layout.css.devPixelsPerPx, Modify, and enter a value of 1.20 or 1.25 or 1.5 or 2.0... the effect can be seen immediately without closing Config. editor. There are pictures to demonstrate different values here.

To Max Barrett: Please edit your last post to state explicitly that the 'step further' applies only to Firefox, not TB, to avoid confusion.

Meanwhile, "Bernie" over at Wan Hung Lo Electronics posted this, and it worked for me on my Mac running OS 10.14.6:

"One workaround for now for scaling:

Go to advanced preferences in Thunderbird and click on Config Editor.

Find “font.size.systemFontScale” (click to open a dialog box) and adjust the scale (do so *gradually*! Try maybe 10-15 increase/decrease at a time until you get to where you want.

Changes will show when you close the Mail window and reopen it (or restart Thunderbird)."

I scaled up to 150. Hope this helps others.

font.size.systemFontScale did make the system fonts a different size in Thunderbird. But this didn't solve my current problem, which is the size of the layout (such as the height of tabs and toolbar), which is the wrong size relative to the size of email text.

I think a perfect solution would let the user choose (in Tools > Options > General) the size of (1) the general layout and font (in points) and (2) the default size of email text (in points). Then all display elements (panels, menus, email text) would be scaled relative to the user's two choices. We need just two easily-set choices, not three or four internal settings. Just my opinion. Most other apps, including email programs, look nice right out of the box, even if the user has set various sizing parameters in Windows.

My settings are the recommended 1920x1080 resolution and recommended 150% text/apps size for my laptop, and I've had to adjust Thunderbird again and again and it still doesn't look right (my opinion).

I agree completely. At 150 on my scale, the type doesn't fit neatly into the allotted space. But I can read it now, and that's a good start! This also happened with the Theme Font and Size add-on, but again it was such an improvement in readability that I learned to ignore it.

I understand the Thunderbird philosophy re add-ons and extensions but in the past, some have been incorporated. I hope the options you outline, or others that would perform as well, will become part of program.
