Increased font size-error

I've accidentally increased my font size from 1.5 to 150% and I cannot see Thunderbird correctly or adjust.

I've deleted and re-installed the program and it has not helped.

My Thunderbird visual screen is way too big to make any adjustments or see where to adjust.

Any suggestions?

Thank you- Terry

I assume you did that in config editor? If so, locate the prefs.js in the profile. It is a simple text file, so do not open it with a word processor. Notepad or the like is preferred. Locate the config entry that you modified and change to a more realistic number. Do this when Thunderbird is not running. To be safe, copy the file before you change it.
