Without this little code, the extension will not download. The download file will be automatically named as extension with its version number for your convenience. Installing Saved Extensions: Chrome policies do not allow installing extensions outside the WebStore. However, there is a workaround for installing your saved extension or extensions from third party sites. To install an extension outside Chrome WebStore, follow these instructions – Step 1. Open your extensions page from Chrome Options > Tools > Extensions or typing chrome://extensions in the address bar.
Now drag and drop your saved extension onto this page. Chrome will confirm the actions. Accept that and you are done. So you see, manually downloading and installing extensions is fairly easy task. In absence of internet connection or in situations when you can’t sync Chrome, this is must-know technique every Chrome lover should know.
