I really hate it when websites don’t give you any warning of links which will open in a new window. A lot of sites provide a little icon, or a small superscript comment, or even a tooltip. However, some don’t.

The one site that really annoyed me was Google’s GMail. I always like to keep the left-most tab in firefox on my Google Personalised Home. When a message arrives, I click the GMail header and am consequently presented with the GMail Inbox. Perfect.

In the top-left corner of the GMail homepage is a link back to Google Home (whether personalised or not - it ‘knows’) which opens in a new window. Which is very frustrating if you have lots of tabs open in the current window. After looking for an ‘Open in this tab’ extension and failing to find one, I decided to create my own.

Enter thisTab! - a Mozilla Firefox extension to override the behaviour for a link which uses the target=’_blank’ parameter to open a new window. Note that this won’t work with javascript popup links.

As this is my first foray into any kind of ‘plugin’ development, I’d love to know what people think.
