how to export extensions of Google Chrome?

or you can use the following command to export

- chrome://extensions/
- shift+ctrl+j
- paste this :
returnExtensionsData=function(a){var o=[];for(var i=0,e=a.extensions,len=a.extensions.length;i<len;i++){o.push({id:e[i].id,name:e[i].name});}console.log('var extdata='+JSON.stringify(o)+';');};requestExtensionsData();

If you want to import , paste the output in the destination browser and run

 returnExtensionsData=function(a){var o={};for(var i=0,e=a.extensions,len=e.length;i<len;i++){o[e[i].id]={name:e[i].name};}importExtensionsData(o);};
 function importExtensionsData(exts){var version=/Chrome\/([\.\d]+)/.exec(navigator.appVersion)[1];var lang=navigator.language;for(var i=0,len=extdata.length;i<len;i++){if(!exts[extdata[i].id]){var url='https://clients2.google.com/service/update2/crx?response=redirect&x=id%3D'+extdata[i].id+'%26uc%26lang%3D'+lang+'&prod=chrome&prodversion='+version;con
