How to reset Thunderbird email to -1.0 default size

more options

Hi, I accidently set the email size in the Config editor layout.css.devPixelsPerPix to 125 (instead of 1.25), which results in the program no longer being able to be viewed as it takes up the entire screen.

How can I undo this please, since the reset option is not viewable due to the immense size now.

The tutorial video I followed is this: https://www.youtube.com/watch?v=klIOX4dsXU4

I appreciate your knowledge, please in simple steps :-)

Thank you, Jana

Hello

Take a look at https://connect.mozilla.org/t5/discussions/layout-css-devpixelsperpx/td-p/42594

Or Check Thunderbird are stopped Then Go to your profile https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data and find your prefs.js file and open with your notepad and delete line user_pref("layout.css.devPixelsPerPx", "125"); And save prefs.js and restart Thunderbird.

I have closed Thunderbird. I read the post. My system language is German. i don`t see the Charms to select Search, unless I am supposed to search on top right, like the screenshot shows. When I do so, there is no result, which might have to do with the language. I cannot open Thunderbird.

When using the alternative (Alternatively, you can find your profile by pressing the Windows Key key and then start typing: %APPDATA%\Thunderbird\Profiles\) there is also no result due to the search term being in English, I suppose

Thank you for your reply, but I need more information please or the correct translation to German for %APPDATA%\Thunderbird\Profiles\

I got as far as to the Roaming folder after making hidden folders visible, however there is no Thunderbird folder in it. See screenshot.
