Why does Browserosaurus ask to be set as my default browser?

This is required for Browserosaurus to know that a link has been clicked. You can change this at any time by going to System Preferences > General > Default web browser and (de)selecting Browserosaurus. Please note that if not set as the default browser, Browserosaurus will not work.

How do I set my favourite browser?

A favourite browser is one that will always appear nearest to the mouse cursor, therefore an easier target to click. You can set your favourite by clicking on the Browserosaurus menubar icon.

The picker window was very slow to display.

The app needs to be running in the background for the picker window to show immediately. You can confirm Browserosaurus is running by looking for the "B" icon in the menubar. If you have not set Browserosaurus to load on startup, it can take a few seconds until it is available. Each subsequently clicked link will open the picker window promptly, like normal.

I'm clicking links in my browser but Browserosaurus does not show.

Only links clicked outside of browsers will open Browserosaurus. This is by design.

Does Browserosaurus collect any of my data?


Not even the link I click?

Nope. The only outgoing call Browserosaurus makes is to check for an update. The only persistent piece of user information saved to disk is which favourite browser you have selected.

I installed or removed a browser but I'm not seeing this updated in the picker window.

Browserosaurus checks for installed browsers when it is loaded. Please click the "B" icon in the menubar, and select "Quit". Start Browserosaurus again and you will see the changes.

I have a browser that's not shown in the picker window, even after restarting Browserosaurus.

Browserosaurus operates on a whitelist basis. If you would like a browser added, please raise an issue.

I have a question that is not answered here.
