That can be possible. I remember seeing the option in a clean profile while using Ubuntu.

There is no container option in new Firefox profile. It appears only after when you’ve installed Multi container extension. Firefox from Arch Linux repo.

I use it to play visual novel type android games.

My very first linux distro is Zorin OS since it is Windows like and heard it is more light weight. After using it for a while, it didn’t feel like more light weight to me so I switched back to Windows.

After some years later, I decided to ditch Windows completely and used Ubuntu 20.04 for about a year. When I broke Ubuntu after using about a year, I switched to Arch and still on Arch to this day.

I use Seal, yt-dlp android front-end, on my phone to download videos from streamming sites.

For torrenting, Deluge on my computer and libtorrent on my android. I mainly use torrent for anime so I download a .torrent file from nyaa and open it with Deluge. Done.
