So I found an article on how to change to font size using config editor and I accidentally left out the decimal point while changing it 1.25 and now the entire Thunderbird screen is blown up/zoomed in like a microscope. I can't change it back. I tried to uninstall and reinstall to no avail. I even attempted using keyboard shortcuts to try and do it like a blind person. Meaning, I used the computer next to me to record the exact same steps using only keyboard and no mouse and then repeat on the trouble computer. For some reason it didn't work. For clarity here are the steps I took using keyboard:

  • press ALT + T
  • press P
  • type "config edit"
  • press TAB
  • press ENTER
  • type "layout.css.devPixelsPerPx"
  • press TAB
  • press TAB (again)
  • press ENTER
  • type "-1.25"
  • press ENTER

Is there another way for a simple person like me can change it back?

Chosen solution

My suggestion is to edit prefs.js. It is in your profile. But first, copy it in case you make another mistake. Do all of this while TB is not running. 1. make backup of prefs.js 2.open it in a simple text editor, such as notepad 3. after the first line that shows userpref, enter this line 

    user_pref("layout.css.devPixelsPerPx", "-1.0");   and press enter. Ensure no blank lines. Save it.

4. Restart TB. I think it will be back to normal. If that works for you, you can use this approach to try other settings.
