Suppose you want to help out a friend or a client to solve any PC issues he/ she is facing, with your expertise on that subject like any software not working properly, to execute any application properly or basic troubleshooting, then the most productive way of doing it would be to provide support through a remote desktop session especially if you live far away from that client or friend.

 

HTTrack is a free (GPL, libre/free software) and easy-to-use offline browser utility. 

It allows you to download a World Wide Web site from the Internet to a local directory, building recursively all directories, getting HTML, images, and other files from the server to your computer. HTTrack arranges the original site's relative link-structure. Simply open a page of the "mirrored" website in your browser, and you can browse the site from link to link, as if you were viewing it online. HTTrack can also update an existing mirrored site, and resume interrupted downloads. HTTrack is fully configurable, and has an integrated help system.
WinHTTrack is the Windows 2000/XP/Vista/Seven release of HTTrack, and WebHTTrack the Linux/Unix/BSD release. See the download page.

 

Creating multiple login accounts on a website is never an issue. Accessing them simultaneously is. Most browsers have their own centralized cookie management system. When you are logged in to a website in one instances, you won’t be able to login to the same website using another account, even if you open a new tab or window. Personally, I have more than 2 Gmail accounts, Yahoo accounts, Facebook accounts and multiple login IDs to my own blog. There are times when I need to login to different accounts to access a particular emails, or to check the setting/status of the other accounts. Below are some of the ways that I used to access to different accounts (of the same website ) simultaneously.

Install multiple browsers

This is definitely not the most effective method, but it is surely one method that works 100% of the time. Since all browsers have their own cookie management system, you can easily login to one account in Firefox, and another in IE/Chrome/Opera/Safari etc. The downside of this is that they clutter up your desktop, take up lot of memory and storage space.

Firefox

To be able to login to various accounts in Firefox, the best way is to install the extension CookiePie. What it does is to create different instances of cookies in different tabs and windows so you can login to the same website with different login ID simultaneously.
1. Install the CookiePie extension from the Nektra site.
2. In the current tab, login to your account with the primary ID
3. Open a new tab, right click at the tab and select Toggle On/Off Cookiepie.

You will now see a cookie on the tab.

4. On this new tab, you can now go to the same website and login with another ID.

Note: CookiePie conflicts with some of the extensions, like Tab mix plus and TooManyTabs. It might not work properly with these extensions.

Internet Explorer 8

Internet Explorer 8 comes with a New Session mode that allows you to start a new window with a brand new session.
Open IE8, go to the URl of the site and login with your first ID.
Go to File->New session. This will open a new window. Navigate to the same site and you should be able to login with another ID.

Google Chrome

Google Chrome comes with a incognito mode that allows you to login to two different instances of the same website.
1. Login to the the website in Google Chrome.
2. Glick on the Tools icon and select New Incognito Window. Alternatively you can press Ctrl + Shift + N to open a new Incognito Window
3. Navigate to the same website and you should be able to login with another user ID.
What other methods do you use to login with different accounts on the same website simultaneously?
