Browserosaurus free download for Mac


30 July 2020

Choose with which browser to open links.


Browserosaurus is a browser prompter for macOS

After clicking a link, use the picker to choose the correct browser for the job.

Keep your usual browser closest to the mouse, at quadruple the size.

The Blue Bar

Make sure the website you are about to open is the one you are expecting.

Browserosaurus is FREE. However, please consider a small donation. Doing so will help me cover the cost of future development.


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 activity?

A favourite activity is one that will always appear nearest to the mouse cursor, will be much larger and 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 activity 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.

If you have any issues, feature requests, or would simply like to say "hi", please raise an issue on GitHub, or send me a tweet.

What's new in Browserosaurus

Version 10.12.1:
  • Add support for Finicky (thanks @anmull).
  • Internal:
  • Built using NodeJS v14.
  • Lots of dependency bumps.
  • Replace classcat with clsx. This is apparently faster (not that we're doing anything intense here) and has the same API as classnames, which I missed.
  • Replace FontAwesome Pro with Free-only packages. I wasn't actually using any Pro icons and it added another barrier to contributors who do not have a Pro license.
  • Installed apps are now detected using Sindre Sorhus's app-exists package, which I helped update

Version: 9.0.1
I often need to view pages linked in my e-mails (I use Thunderbird). The browser that I use is dependent on the content format of the page because of the different formatting capabilities of each browser I use. Browserosaurus makes it easy to open up the desired browser. Even if a browser I want to use is not registered in Browserosaurus, there is a copy link option with it for me to copy and paste into a browser that I don't normally use. A handy and time saving app.

Version 6.7.0 is the "initial release?" How does this compare to BrowserChooserX, which is also free?
