To day I was surfing the internet in Linux and using Firefox. But suddenly I noticed that there is an interesting useful feature in the Firefox. What’s that? You can copy just selecting the text and paste it by middle click in Firefox. It impressed me so much and I’ve made it my habit.

But when I returned to Windows XP and tried to imply my earlier experience it failed. So after some investigation I found the way to enable the same feature in Firefox In my Windows XP. Read the following simple guide to enable the select-to-copy and middle-click-to-paste feature in windows XP. You might be introduced with the phrase about:config. It is nothing but the command to browse the Firefox own configuration treasure. Here you can configure the above feature to enable it in the current operating system.
How to enable select-to-copy and middle-click-to-paste in windows
- Launch Firefox and type about:config in the address bar.
- Now a message like this will appear:
- Click on I’ll be careful, I promise!
- In the filter bar type “middlemouse.paste”.
- By default the entry middlemouse.paste is false in windows. To enable it just double click on it or right click on the entry and then click on Toggle to make it true
Another entry in the Firefox configuration page is clipboard.autocopy to copy the content in the clipboard when selecting. But this feature works well in Linux + GNU and true by default and in windows it is false and it still does not work if you toggle it to true.
Tip: Speed Up Your Firefox Browser
However you can also avoid the manual configuration and also enable the select-to-copy by a Firefox plugin AutoCopy. Just download it and install. Remember to disable the manual configuration in the about:config if you’ve enabled the middlemouse.paste entry otherwise it will paste the content twice. You can make some changes in the plugin configuration from the options button. 
Please let me know if you know about any other way to perform the same job.
You could use the smaller extension ClickCutter AutoCopy.

@StN: Thanks for your link though I have already written about both the manual process and addon. Anyway our readers may be benefited from your link. thanks again.
Thank You! This is one of the most annoying aspects of using a Windows Box, and it always takes me a long time to remember how to fix mozilla on windows.
AC, I also agree with you.
FYI – middle-click copy/paste in Linux has nothing to do with Firefox. It’s a standard feature of the X11 server that is used by most unix-like systems to handle mouse input.
