About this extension
The Monaco editor works well with large files, which is not the case with the regular Firefox viewer. This extension integrates a stripped-down version of monaco-editor-0.52.2 when viewing a document with the json content type. It has automatic support for light and dark themes, as well as support for a list of languages en, ru, de, es, fr, it, ja, ko, ZH-cn, zh-tw (determined by browser settings)
