Nothing new here

There are many reasons why you would want to fake your location in firefox. One good reason would be "un-faking" your location on computers with no wlan cards, e.g. at work, or where there's no data available for the WLANs around you. All you need for faking is a text file (eg. /home/username/.mynewlocation.txt) somewhere on your computer with the following content:
{"location":{"latitude":50.941863,"longitude":6.958374, "accuracy":20.0}}

The path in Firefox to this file is:
file://home/username/.mynewlocation.txt

Type about:config in your location bar, confirm the warning, search for geo.wifi.url, and replace the old url (https://www.google.com/loc/json) with your new one from above. Restart firefox, enjoy your new location :-)

Explanation:
latitude/longitude => the location you want to have, go to google maps, select location, click on "Link" and use the values from the ll= parameter
accurancy => the accurancy you want to announce, in meters.

This is just a quick JS example of connecting Openstreetmap, through Cloudmade, with the new geolocation in Firefox 3.5. Now all I need is a great idea how to make something much more useful out of these two :-)

Locate me

1. Click 'Locate me'.
2. in Firefox 3.5 allow location sharing by clicking "Share location"

The code is uncommented, since it's straight forward, once you had a look at the CloudMade docs

<button onclick="locateMe();" src="">Locate me</button><br/>
<div id="pugio-osm" style="width: 460px; height: 400px"></div>
<script type="text/javascript" src="http://tile.cloudmade.com/wml/latest/web-maps-lite.js"></script>
<script type="text/javascript">
  var cloudmade = new CM.Tiles.CloudMade.Web({key: '7f203ab42017580cb27688d55067ca06', styleId:997});
  var map = new CM.Map('pugio-osm', cloudmade);
  map.addControl(new CM.LargeMapControl());
  map.setCenter(new CM.LatLng(0, 0), 1);

  function locateMe()
  {
    if (navigator.geolocation)
    {
    //yes, the location in Ff3.5 is basically a one-liner
      navigator.geolocation.getCurrentPosition(function(position)
      {
       //position holds our coordinates
        var myLoc = new CM.LatLng(position.coords.latitude, position.coords.longitude);
        
        var myMark = new CM.Marker(myLoc, {
          title: "You are here"
        });
        map.setCenter(myLoc, 15);
        map.addOverlay(myMark);
        myMark.openInfoWindow(
        "<a href=\"http://www.flickr.com/search/?a=14&b="
        + map.getBounds().getSouthWest().lng() 
        + ","
        + map.getBounds().getSouthWest().lat()
        + "," + map.getBounds().getNorthEast().lng()
        + "," + map.getBounds().getNorthEast().lat()
        + "&z=t\" target=\"_blank\">Photos on Flickr</a>");
      });
    }
    else
    {
      alert("Sorry, your browser does not provide an location API\nor you disabled it (geo.enabled=false in Firefox 3.5).");
    }
  }
</script>

As a heavy-user of Firefox, the biggest annoyance in Safari for me was the missing shortcuts for directly accessing tabs. In Firefox you can access the tabs by pressing Cmd+<number of tab>. For example, if you want to jump to your third tab you would press Cmd + 3 (⌘ + 3), however in Safari this loads the third bookmark from the bookmark toolbar - very annoying if you are used to a different behavior.

Luckily there is a way to change this behavior and make Safari (4, not sure about 3) behave like Firefox with the help of this innocent looking piece of AppleScript:

tell front window of application "Safari" to set current tab to tab 3

Simple, isn't it? Now, all we need to do is to figure out how to combine this script with the shortcuts. Thankfully there's a small and free application called FastScripts Lite (hidden on the bottom of that page), it's limited to ten shortcuts, but all we want are nine (since Cmd + 0 is assigned to a somewhat useful "Actual Size" function), so it's perfect. If you need more shortcuts, you can purchase the full version.

Let's review that AppleScript above to ignore any errors caused by non-existing tabs:

try
	tell front window of application "Safari" to set current tab to tab 3
on error
	tell front window of application "Safari" to set current tab to last tab
end try

Open Script Editor and create nine files from 1-9 in ~/Library/Scripts/Applications/Safari, let's call them Tab1.scpt to Tab9.scpt and paste in each file the script from above, changing the 3 at the end of the long line to the current number. I have prepared a Zip with all nine files (SafariTabs.zip), so you don't need to do this by yourself. Simply extract this file in ~/Library/Scripts/Applications/.

Next, launch FastScripts, click on the icon in the toolbar at the top of the screen and go to FastScripts->Preferences:

1. We want FastScripts to start when we log in.

2. Assign Cmd+1 - Cmd+9 (or any other combinations) to the proper Tab-scripts

Go back to Safari, and see the magic at work!
