I have been using the below link format for the past few years to download crx files from the chrome store.
https://clients2.google.com/service/update2/crx?response=redirect&prodversion=[PRODVERSION]&x=id%3D[EXTENSIONID]%26uc
Since last week this method no longer appears to be working for me, has anyone else encountered this and found a way around it? has this method become deprecated?
