How to close chrome tabs with keyboard shortcuts?

Question

Browsers

How to set up closing a tab in a chrome or firefox browser by pressing, for example, the right mouse button, i.e. not on a cross, but anywhere you press the right key and ctrl + w is emulated? You don't need it often, so you need a quick ability to turn this feature on and off, you can reboot if the script.
I tried xbindkeys a lot of gestures and all sorts of configs, I want a simple solution, something like an add-on for chrome.

Answer 1

In chrome, the tab is closed with the middle button on the taboo.

Answer 2

In the developer version of Opera, you can change the combination for closing a tab to any one button right in the settings. But, unfortunately, only on the keyboard button.
Even in the same opera, you can close it with a gesture down-> to the right with the right button pressed.
In principle, there are extensions for gestures in any browser, maybe this is just what you need.
