# Computer tricks

## How do you get the streaming URL for radio stations? [1]

Use [RadioBrowser](http://www.radio-browser.info/).

## Super+Q doesn't close applications in Pop Shell. Sometimes it shows numbers on the taskbar. [2]

Run `gsettings set org.gnome.shell.extensions.dash-to-dock hot-keys false`.

## How do you remove the tab bar in Firefox? [3]

* Go to Menu -> Help -> More Troubleshooting Information and find the profile directory. 
* Create `chrome/userChrome.css` in it with `#TabsToolbar { visibility: collapse !important; }`. 
* In `about:config`, set `toolkit.legacyUserProfileCustomizations.stylesheets` to True.

## You have a name resolution failure and your VPN might be causing it.

Do `nmcli connection delete [connection name]` for anything suspicious.
