Does anyone know if Tor can be used with browsers other than the built-in Browserd?

I would like to use Tor with FIrefox or Opera, but it appears Tor only works with the built-in browser (while Tor is on if you go a a page using Opera or Firefix you will be connected directly, not via Tor). Perhaps there are comoand line switches on Opera or Firefox which can be used to enable the browsing via the SOCKS connection, which is required for Tor? (it can probably be done via the about:config connection settings, but that is a major pain, a command-line switch would be a lot easier).

For example, if you use the text-based browser called Links installed on the N900 all you would do is type at the command line

and you will browse via Tor (as long as it's enabled and connected).

Is there anything similar for Opera, Chorium or Firefox?
