Answer 1

You can use the below URL template,

https://clients2.google.com/service/update2/crx?response=redirect&prodversion=[PRODVERSION]&x=id%3D[EXTENSIONID]%26uc

The PRODVERSION is the Chrome version. (get it from settings -> Help -> About Google Chrome). Ex : Version 69.0.3497.100 (Official Build) (64-bit)

The EXTENSIONID is the id for the extension. Ex : Here is a sample plugin, https://chrome.google.com/webstore/detail/jetbrains-ide-support/hmhgeddbohgjknpmjagkdomcpobmllji?hl=en the id is hmhgeddbohgjknpmjagkdomcpobmllji

So sample request to download will be https://clients2.google.com/service/update2/crx?response=redirect&prodversion=69.0.3497.100&x=id%3Dhmhgeddbohgjknpmjagkdomcpobmllji%26uc

Create a bookmark add the javascript function as the address. Browse to the chrome extension you want to download then click on the bookmark and it should start downloading.

javascript:(function(){
    var pathname = location.pathname;pathArray = pathname.split("/");   
    location = ("http://clients2.google.com/service/update2/crx?response=redirect&x=id"+"%" + "3D" + pathArray[pathArray.length -1]+"%" + "26uc%" + "26lang%" + "3Den-US&prod=chrome"); })();

Thanks

None of the manually ways in this post works for me so i searched for a URL to download the extension direct. Find this and works perfect for me.

https://clients2.google.com/service/update2/crx?response=redirect&prodversion=49.0&x=id%3D###EXTENSION_ID###%26installsource%3Dondemand%26uc

You must replace ###EXTENSION_ID### with the extension id from the chrome shop. Its part of the URL.

Example Google Translate Extension:

https://clients2.google.com/service/update2/crx?response=redirect&prodversion=49.0&x=id%3Daapbdbdomjkkjkaonfhkkikfgjllcleb%26installsource%3Dondemand%26uc
