File extension crx is associated with Google Chrome, a web browser developed by Google which uses the WebKit layout engine and application framework.
The crx file contains extensions and plug-ins for the Google Chrome Internet browser (skins, function extensions). The crx file format is just a variation of the ZIP archive used by Google Chrome.
An app's crx file can be hosted on your server or, more typically, by the Chrome Web Store.
Microsoft Edge browser is also based on Google Chrome core and thus supports extensions and plugins designed for Google Chrome.
The *.crx file format is associated with and used by the Google Chrome Internet browser. The file contains extensions for Google Chrome.
The *.crx files are ZIP archives with renamed file extension to crx. You can rename the crx file extension back to ZIP and open the ZIP archive file in any compression utility, such as WinZip, WinRAR, or PeaZip.
There is no easy way to convert *.crx plugin files to other formats. Try to use the crs-to-xpi tool to convert the Chrome extension to Firefox, but the result is not guaranteed.
