Ubuntu default browser from Firefox (default) to Brave

gistfile1.txt

First, check if the `brave.desktop` file is present in `/usr/share/applications`.
If not, just create a symlink like that:
```
ln -s /snap/brave/current/meta/gui/brave.desktop /usr/share/applications/brave.desktop
```

Then edit the `default.list` file:
```
sudo nano /usr/share/applications/defaults.list
```

Change this:
```
x-scheme-handler/http=firefox.desktop;
x-scheme-handler/https=firefox.desktop;
```

To that:
```
x-scheme-handler/http=brave.desktop;
x-scheme-handler/https=brave.desktop;
```

And voilà!
