Firefox Extension ?

I'm not currently working on anything, but I'm sure its possible.

Most of the heavy-lifting for lastSlacker is done with client-side javascript, so my guess is a Firefox extension could reuse much of this code. I don't have much motivation to do this however, because I prefer being able to support most modern browsers.

The server side is actually pretty simple. All it does is take simple requests from the javascript client, and handle the communication protocol with last.fm. There isn't much of a security concern regarding passwords, because the client-side javascript handles encrypting your password based on session data received from last.fm, so your real password never leaves your browser, and lastSlacker.com has no way of figuring out what it is.

Because Slacker is javascript based rather than flash based like pandora, I was able to more tightly integrate last.fm support. For this reason, I don't think there is as big a need for an extension as you don't have to do cumbersome things like log-in to pandorafm in order to use it anyway. Perhaps a greasemonkey script to automatically load lastSlacker and log you in to last.fm whenever you visit slacker.com would make the process even more seamless... Maybe somebody with some greasemonkey experience wouldn't mind whipping this up...

I haven't tried this yet, but a lastSlacker user by the name of Kevin whipped this up:
--------------------------

Very simple. Copy in-between the ######### lines and name the file lastslacker.user.js
Install Greasemonkey. Install this js then you don't need to run the bookmark.

OK, tried it in Firefox 3 beta 5 with Greasemonkey 0.8.20080121.0 and it still locks up

From what I can tell Firefox 2 is the way to go here. Thanks to all.

here is the update/workaround:

var body = document.getElementsByTagName('body')[0];

body.appendChild(bootstrap);


},

false);

function checkLoad(){

if(document.getElementById("player")){
alert('Wait for the Loading Radio Stations.... Then Click OK');
return true;
}else{
checkLoad();
}

Here is the FF3 code that auto places it after 10 seconds (no alert box). Feel free to change the 10000 to a higher number if you are on a slow connection.
