Duplicate a tab — with a twist.

For developers and testers who live in the URL bar
Sometimes you need the same page again — but with a debug flag, a feature toggle, or a different locale. The Duplicator clones your current tab and appends the parameters you define, saving you the manual edit every single time.
Define presets once and reproduce complex states with a single click.
How it works
01
Define your presets
Create named parameter sets like ?debug=true or ?locale=fr you use often.
02
Duplicate a tab
Click The Duplicator and pick a preset to open a copy with those parameters applied.
03
Iterate faster
Compare states side by side without ever touching the address bar.
