I have just started using Linux Mint 20 and I have Thunderbird 78 installed My Problem is font size but NOT of the actual email.. 

I can change font size of the actual email content using ctrl and the mouse.
I am trying to increase font size of the panels ..  If that is the correct term for them

I have tried the settings in the options menu with no results.

I CAN adjust sizes of everything except the actual font size by changing layout.css.devPixelsPerPx;1.5 through the config editor. 

Everything else DOES get bigger except for the text.  Changes here appear to add a whole lot of white space, make the icons bigger, info windows bigger, etc., but does n not change the text.

I made the same changes to my windows 10 system and everything worked as it should....???

Help, Anne

Use this code instead: 

.tree-rows
{
  font-size: 12pt !important;
}

Are you referring to the fonts in the Folder and Threads Panes, i.e. the folder names in the left pane and the list of Subject, Date, From etc. in the pane with message headers? That can be done with userChrome: 

#threadTree
#folderTree
{
  font-size: 12pt !important;
}

Help/Troubleshooting, Profile Folder, Open Directory, close TB, create a new folder named chrome, create a new document in chrome with a text editor, name it userChrome.css, Save as type: All files *.*, copy in the above code, change the number as desired. Double-click toolkit.legacyUserProfileCustomizations.stylesheets to true in Edit/Preferences/General/Config. editor, restart TB.

It doesn't work for me anymore in the latest version. I found this solution:

For Linux go to Preferences For Windows go to Tools > Options Then General > Config Editor (at bottom) Accept risk Change this: font.size.systemFontScale 100 > 110, 115, ....

The code posted above does work in TB 91. Check that you followed all the instructions, to the letter.
