The fastest (yet safe) add-on to close tab using mouse only! Close any tab by double clicking the tab. Close current tab by triple click anywhere on the page. Optionally middle click or double right click on page to close tab.
Here is a little more about the add-on from the developers:
This addon brings the much needed relief for the mouse addicts :) You can:
- Double click anywhere on any tab to close it (no need to find ‘x’ button, which might not even be there)
- Triple click anywhere on webpage to close the current tab. Optionally, double right click or middle click to close the current tab. For the adventurous, double left click to close is allowed; for the super-conservative, you can disable closing tab by click on page altogether.
Just give it a try – speed is guaranteed!
