You might have needs to open multiple FireFox instances at once for multiple tasks, it’s not just open more and more tabs, but also cookies, authentication session, website, bookmarks, online accounts….That mean multiple FireFox, multiple workspaces/

If you’d love to like so, here is tips to do

1. Download FireFox Portable Editon from portableapps.com.
2. Run file you have just downloaded, it will extract to where you choose to place your FireFox Portable
3. Open folder you have just extracted and looking for files [FireFox Portable]\Other\Source\FirefoxPortable.ini
4. Open FirefoxPortable.ini and change AllowMultipleInstances=false to AllowMultipleInstances=true
5. Save FirefoxPortable.ini
6. Copy FirefoxPortable.ini to root folder of [FireFox Portable]
7. Clone folder [FireFox Portable] as many as you’d like, each of them will be a single FireFox instances
8. Each time, just choose a folder of them and run FirefoxPortable.exe
9. Hope you love it.

You need to make some changes in web.config file in order to get it work.

The easest way is to download an updated web.config here (thanks to ASPone’s wiki).

Matt Williamson have suggest two solutions which both work fine

Solution 1.

   1: using System;

   2: using System.Collections.Generic;

   3: using System.Linq;

   4: using System.Web;

   5: namespace MyProject.WebSite

   6: {

   7:     public class PageBase : System.Web.UI.Page

   8:     {

   9:         protected void Page_PreInit(object sender, EventArgs e)

  10:         {

  11:             // This is necessary because Safari and Chrome browsers don't display the Menu control correctly.

  12:             // All webpages displaying an ASP.NET menu control must inherit this class.

  13:             if (Request.ServerVariables["http_user_agent"].IndexOf("Safari", StringComparison.CurrentCultureIgnoreCase) != -1)

  14:                 Page.ClientTarget = "uplevel";

  15:         }

  16:     }

  17: }

 

Then make sure all of your pages get inherit from this PageBase.

Solution 2.

   1: if (Request.UserAgent.Contains("AppleWebKit")) Request.Browser.Adapters.Clear();

I'm remember that some one have done a smart declarative browser adapting solution which we can control ASP.NET Render to render fine-tuned HTML code for selected Browser in Web.config, but now can't find it back. Please lets me know if you find it around.

AOL Instant Messenger (AIM)

AOL Instant Messenger (AIM) ids can be represented using the aim: protocol. Many who publish their AIM ids do so with clickable URLs e.g.:

<a href="aim:goim?screenname=ShoppingBuddy">IM with the AIM ShoppingBuddy</a>  

Yahoo Messenger

Similarly, Yahoo Instant Messenger (YIM) ids can be represented using the ymsgr: protocol. And similarly many publish their YIM ids as clickable URLs e.g.:

<a href="ymsgr:sendIM?SomeYahooFriend">IM with SomeYahooFriend</a>

MSN Messenger

MSN Messenger (MSNIM) ids can be represented using the msnim: protocol. And similarly many publish their MSNIM ids as clickable URLs e.g.:

<a href="msnim:chat?contact=joebob@hotmail.com">IM with joebob@hotmail.com</a>

XMPP (Jabber) 
Extensible Messaging and Presence Protocol (XMPP) (http://www.xmpp.org/) ids can be represented using the xmpp: protocol, e.g.: 
<a class="url" href="xmpp:username@jabberservice.com">IM with username@jammerservice.com</a>

Skype 
Skype can be represented using the skype: protocol. It can be used to open a chat session or make a Skype call. 
<a href="skype:echo-chinese?chat">IM with the Skype echo service (Chinese) </a>
<a href="skype:echo-chinese?call">Skype call to Skype echo service (Chinese) </a>  

ICQ 
ICQ does not have a URL scheme. Rather ICQ links on the web use HTTP hyperlinks to download a resource of content-type application/x-icq which then the operating system opens with the user's ICQ client. 
Thus we can markup those HTTP hyperlinks with the content-type set explicitly to communicate the ICQ semantic: 
<a class="url"
   type="application/x-icq" 
   href="http://www.icq.com/people/cmd.php?uin=[ICQNUMBER]&action=message">
 Contact with ICQ</a>

Replacing [ICQNUMBER] with the user's actual ICQ number.

When you share a Folder from a Windows XP machine, you might not able to access to it even you see that computer in it's work group, any time you attempt to access to, you receive a error message like

• \\[SHARE] is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have  access permissions. 
• Logon failure: the user has not been granted the requested logon type at this computer

When ran into it, you can consider one of two solution I found from others over Internet. It  might help a lot.

Audit Local Security Settings

1. On Start Menu>Control Panel>Users, enable Guest user.
2. Open Local Security Settings by select Start Menu>Control Panel>Administrative Tools>Local Security Settings
3. Navigate to Local Policies>User Rights Assignment
4. Right-click on Access this computer from the network>Properties>Add Users or Groups, add everyone or any users you want to be able to access the computer from the network > Add Guest user to this if not exists
5. Right-click on Deny access to this computer from the network>Properties, remove everyone or any users you do NOT want denied to be able to access the computer from the network > Remove Guest user from this if exists
