Chrome Extension to Sell More Reqs

Hello,
So many of you about the chrome extension that allows you to sell more than one req card at a time. I can link this if anyone needs it. I would love to use this but I don’t want it to void any of my progress in the game. I’m on the grind to SR 152 for the reward in Halo: Infinite, but I don’t want this extension interfering with this or somehow making my stats in-game void, as I would be using a third party extension. I just don’t want to lose all my progress or break some rule in the terms and conditions of the game. I’m not very familiar with these types of things so if someone could answer my question I would appreciate it. Thank you :smiley:
