How to load extensions using Rselenium

Can anyone give me a hand to figure out how to activate a chrome extension with RSelenium?

Extensions are located in the tab of the browsers, but are not preloaded when using RSelenium.

This is the solution I found.

1. Convert the extension to a .crx file.

   step a. navigate to chrome://extensions/

   step b. click on "developer mode"

   step c. click on pack extension. Here I assume you already have the extension up and working.

   step d. browse to the folder where the extension was saved. Commonly around this place:

   C:/Users/YOURUSERNAME/AppData/Local/Google/Chrome/User Data/Default/Extensions/ekhagklcjbdpajgpjgmbionohlpdbjgc/5.0.114_0

   step e. click "Pack extension" this will create a .crx file of your extension, which will be placed in the same path as above.

2. Load the .crx file as part of the preferences for chrome

   #Adjust path accordingly. You can rename the file if you like
   
   PathToCRX="C:/Users/MyExtension.crx" #
   
   cprof <- list(chromeOptions = 
            list(extensions = 
                   list(base64enc::base64encode(PathToCRX))
            ))
   
   
   rD <- rsDriver(port = 4444L,extraCapabilities=cprof, browser ="chrome",chromever = "latest")
