I inadvertently changed the size of my bookmark bar to 125 instead of 1.25’ for ‘Firefox’. Now I can not maneuver to get back to about:config to correct my mistake

Hello

https://support.mozilla.org/en-US/questions/1523792

Is it about, layout.css.devPixelsPerPx

If it's really hugely exaggerated ... The configuration editor is no longer accessible In this case, the solution is to stop Firefox start Firefox stop Firefox

Then in the user profile https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data Open prefs.js with the notepad Search layout.css.devPixelsPerPx and reset to the default value -1.0

user_pref("layout.css.devPixelsPerPx", "-1.0");

Save prefs.js Start Firefox
