If your BitBox02 and MyEtherWallet are not working as intended and you are using Brave browser you may want to temporarily disable Brave Shields to make them work. Find out how below.
- Make sure BitBoxBridge is installed (see "Issue: Bridge not found" in MyEtherWallet Troubleshooting).
- Click on the Brave icon next to the address bar as shown in the image below:
- Next to the line 'Shields UP for this site' in the pop-up message, click on the slider to disable shields.
- Hit F5 or refresh the page in case it doesn't do it automatically. BitBox02 should be read now.
