It will change according to your browser's theme. If you want it to be the theme of your choice, you have to set it from the "Extension Settings" or "Extension Options." To change the default formatting option and other settings, set your desired option in the extension settings. To make JSON Formatter work properly on all kinds of sites, in the extension permissions, change "Allow this extension to read and change all your data on websites you visit" from "On Click" to "On all sites," if not already set. To use JSON Formatter in local files, enable "Allow access to file URLs" in the extension settings. To use JSON Formatter in Incognito mode, enable "Allow in Incognito" in the extension settings.
