Salesforce inspector

Best Original tool but as it's not maintained I would suggest to look for Alternative such as SF-Toolkit that is an unofficial replacement maintain by Salesforce Engineers and largely used internally.

For your information, when an extension reaches its end of life, it's the perfect opportunity for scammers to try to distribute poor quality or even malicious extensions. If you search, you'll find "Salesforce Inspector Reloaded" in my opinion that is the better replacement. But make sure to thoroughly verify/check before installing any extension that will have access to your entire Salesforce.

I haven’t added any new features—just wanted to keep it working for those who appreciate it as much as I do. Thank you, Søren Krabbe, for creating such a great tool!
