What is a NEX file?
A NEX file is a .ZIP file saved in the open Navigator Extension (NEX) format for browser add-on development. It contains all the files and folders for an extension and is used to install browser add-ons, like adblockers. NEX files support a large amount of the Google Chrome web browser (Chromium) extensions.
NOTE: Opera runs Chromium's CRX files as long as the extension uses the chrome specific APIs that Opera supports.
