I'm running Tbird 78.8.0. Others have had this problem and the solution was discussed for Windows, but I'm confused about how implement it on Mac. I copied over a Profiles folder from another computer hard drive to a laptop running Big Sur 11.2.2, and though the contents of the file seem to be all there, the font of the application interface is too tiny for these burned-out eyes to read.
I deleted the add-on for themes and fonts that came with the profile, but that made no difference. Changing the font size in the Preferences pane makes no difference. Starting in Safe Mode makes no difference.
Is there a file I can simply delete somewhere that would reset the IU font size to something readable?
I will be eternally grateful if someone can help. _______________________
I applied the directions for the Windows cure, mutatis mutandis, and it worked perfectly. I respectfully request that this question be deleted unless the manager of this site thinks it would be useful for someone.
The solution was posted by Toad Hall, and is here adapted a bit for Mac users:
Go to 'Preferences' under the boldfaced 'Thunderbird' menu Select 'General' - At the top of the left pane, select "General" (It may just open to this pane.) 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.
I will just add that I found that the value was 1, and I had to boost it to 2 to get the display okay.
