Windows only: We now have a software called SLURL Proxy that makes it very easy to adjust your SLURL settings, in order to open any viewer you have installed.
See here for details

Other suggestions below.

General Windows Instructions

  1. Open Default Programs by clicking the Start button and then clicking Default Programs.
  2. Click Associate a file type or protocol with a program.
  3. Click the file type or protocol that you want the program to act as the default for.
  4. Click Change program.


In Firefox, goto Tools → Options → Applications Tab and scroll to Secondlife. Look to see if Firestorm is listed, if not, select “other”, then browse your hard drive to find the Firestorm.exe, click on it, select Open, then click Ok. (Reference: Applications panel—Set how Firefox handles different types of files.)


Download and install the regular SL viewer - but don't run it.


Try this if the above does not work:

Internet Explorer, Chrome and Safari

Download and install the regular SL viewer - but don't run it.


If none of the above works, then try this as a last resort fix. Go into Chrome settings, the advanced Settings, at the bottom, then Reset Chrome. Please note that this will wipe all your customized Chrome settings.

Mac OS X

The application that handles a URL is a system-wide setting, not tied to any one browser. You can change the setting like this:

  • Download RCDefaultApp 2.1 from the RubiCode download page. Yes, it really will run on current versions of OS X, even though it also runs all the way back to 10.2.
  • Install it according to the instructions int he README file.
  • Go to the Apple menu at the top left. Select System Preferences… then Default Apps (near the bottom), then the URLs tab. Now scroll down until you see secondlife in the list on the left. Click on it.
  • Now select the application you wish to use.


  • Open Firefox and in the address bar type in “about:config”
  • Now right click anywhere on that page and choose New and then Boolean to create a new Boolean entry, when prompted for the name of the entry enter “network.protocol-handler.expose.secondlife” (without quotes) then set the entry to 'false', click ok and your just about done.
  • Now the next time you click a slurl you will be prompted to choose an application to open it with, just browse to the folder you installed Firestorm into and select the file named 'firestorm' (a shell script file). Then before you click Ok, make sure you check the little box to make Firefox remember your choice on how to open slurls. 1)

Work Around

There is an alternative to clicking a link in a browser to have it pass control to the viewer. Some actually find this work around to be faster and use it normally:

  • right click the SLURL link in your web browser and copy to clipboard
  • in the viewer, paste the link into your local chat and hit Enter.
  • open local chat history
  • click the link shown there; you will be shown the location info with the option to teleport direct to it.

The fist thing to check is the viewer settings: Preferences → Network & Files → Connections, in the Web Browser section, make sure Use My Browser… is selected.

If you get an error saying that no program is associated with the action, or that it doesn't know how to hand that action, make sure your computer settings show that there is a default web browser. An easy way to tell is to open your browser; if you are asked to make it the default, then you need to do so.
