Ah I didn't know they've finally done that. I'll have to give it another try. If the password manager works well (e.g. with apps) and I can make the app drawer search open in Firefox then I'll probably switch.
Curious about you mean here. On my android phone the "search for more apps" link in the app drawer search goes to the Play Store app. Why would you want it to open a browser?
After investigation it's actually a feature of the Pixel launcher. In the app drawer there's a search bar that searches apps and the web. It opens search results in the "Google" app, and when you click one by default it uses Chrome.
I found you can make it use Firefox by disabling the setting "Open web pages in the app".
