Increase the number of simultaneous XmlHttpRequests in Firefox

Firefox doesn't do a lot of simultaneous AJAX (or any kind of HTTP) requests. IE caps it at 2, too. This will allow you to test your XHR overload scripts, or just load pages faster in general.

1. Go to "about:config"
2. Find and edit the following
* network.http.pipelining=false
* network.http.pipelining.maxrequests=4
* network.http.proxy.pipeline=false
3. Make the false's true; I set my maxrequests at 20

Open Firefox in Safe Mode

// opens Firefox with extensions disabled. Also gives you the ability/option to reset Firefox to defaults.

// More info and code for other platforms can be found at

/Applications/ -safe-mode

Disable Shift+Click selection in browsers

I wanted the table to allow the user to select a range of rows with a Shift+Click… The problem is that, by default, the browser will select the page’s text content. This isn’t something you’ll want to do very often but it is possible to get around this:

Firefox can do this from your CSS:

table {

    -moz-user-select: none;
On the table element IE needs:

the_table_node.onselectstart = function () {

    return false;

Fix Firefox search engine ordering

1. Type about:config at your Firefox address bar.
2. Type at the filter bar.
3. Change to Google.

The new extension broke my search engine order... cheeky plugin placed itself #1

Getting rid of 'port has been disabled for security reasons' in Firefox

1. Type about:config at your Firefox address bar.
2. Right click -> Select 'New String' -> Type
3. Enter your ports

I allow port 113 for various sundry firewall-related reasons

Clear form with Javascript

Purpose: Clear all text fields in a form

Other important features:
- Resulting page must be valid XHTML 1.1
- JS must work in Firefox 1.0 and MS Internet Explorer 6.0
- JS must never generate any errors, even non-fatal ones, in the Firefox Javascript Console
- JS should only clear text input (no hidden fields or visual controls)
- Code must be readable and properly indented

Looking around the web, this was not easy to find. After a few hours of searches, and some back'n'forth at Webmaster World, I got a working version.

In XHTML header:

<script type="text/javascript" src="clear-form-input.js">script>

In html/form/div

<script type="text/javascript">
  // CDATA[
    var el = document.createElement("input");
    el.setAttribute("id", "clearButton");
    el.setAttribute("type", "button");
    el.setAttribute("value", "Clear");
    addEvent(el, 'click', function(){ clearForm('delicious');} );
  // ]]>

In clear-form-input.js:

function clearForm(formIdent) 
  var form, elements, i, elm; 
  form = document.getElementById 
    ? document.getElementById(formIdent) 
    : document.forms[formIdent]; 

        if (document.getElementsByTagName)
                elements = form.getElementsByTagName('input');
                for( i=0, elm; elm=elements.item(i++); )
                        if (elm.getAttribute('type') == "text")
                                elm.value = '';

        // Actually looking through more elements here
        // but the result is the same.
                elements = form.elements;
                for( i=0, elm; elm=elements[i++]; )
                        if (elm.type == "text")
                                elm.value ='';
function addEvent(elm, strEvent, fnHandler)
        return ( elm.addEventListener
        ? elm.addEventListener( strEvent, fnHandler, false)
        : elm.attachEvent( 'on'+strEvent, fnHandler)

proxy.pac file for Firefox / Mozilla / et. al.

Quite useful for mobile users who work at different locations and require different proxy server settings for each location, just point your Automatic Proxy Configuration URL to your local proxy.pac file and it automatically pics up if it should use a proxy server or not.

function FindProxyForURL(url, host)
   if (isPlainHostName(host) ||
       dnsDomainIs(host, ".foobar"))
       return "DIRECT";
        if (isInNet(myIpAddress(), "", ""))
            return "PROXY; DIRECT";
            return "DIRECT";
