After installing the Ubuntu 18.04 LTS version yesterday, we downloaded Chrome (version 68.0.3440.106) and Switchyomega, and originally planned to install it offline with the result that "you can't add apps, extensions, and app scripts from this site", search for reasons, Google's Chrome browser announced that starting from the latest version of Chrome, the default is only allowed to download and install extensions from the Chrome Web Store, which is frustrating. It is very difficult for the domestic small partners to suffer. Check the information on the Internet to find other students also found this problem, you can start the resolution by the command line:
[Email protected]:~$ google-chrome--enable-easy-off-store-extension-install
Then you can enter it in the address bar as before
chrome://extensions/
You can install the offline Chrome plugin via drag-and-drop or file finder.
Ubuntu Chrome can't add apps, expand programs or scripts from this site
