If anyone from Valve is reading this, my biggest wishlist from Steam OS is a proper general purpose browsing tab. Please make it happen ..
I currently use that web browser from Decky loader, but that keeps breaking so often. Plus it would be nice to have something that i can login my YouTube, Netflix etc.. accounts ..
Did you try loading the browser as a non-game application?
To be honest, I primarily do my browsing offline, and I installed https://localsend.org using Flatpak to move files to/from the Steam Deck. It works amazingly well.
You can install Microsoft Edge from Flathub. (And I think maybe Chrome too?) Edge has the advantage that XBox Cloud Gaming works on it.
Install in Desktop mode, then add as a “non steam game”
