Hi cherrykook,
Thanks for contacting Apple Support Communities!
We understand that you'd like to choose which browser to open links in when you tap a link.
You can choose a default browser which would open that particular browser each time you tap a link as outlined here: Change the default web browser or email app on your iPhone, iPad or iPod touch – Apple Support
"How to change your default web browser or email app
- Go to Settings and scroll down until you find the browser app or email app.
- Tap the app, then tap Default Browser App or Default Mail App.

3. Select a web browser or email app to set it as the default. A tick will appear to confirm it's the default."
We hope this helps you.
Cheers!
