Trezor-bridge download

When plugging my wallet into the computer while I was online, I was instructed to download a trezor bridge application in order to connect my trezor to the web via I was wondering if this is normal?

I had this happen as well. But my bridge was already installed. For some reason, it had stopped running. I did a restart of my computer and it fixed the issue.

Have you done transactions before with your trezor?

No, It was my first time connecting it to the internet and I just wanted to know if everyone had the same experience of downloading an app for, it had me concerned initially.
