Power Close for the Firefox browser is a useful add-on for users of the browser who have more than a handful of websites open in the browser at any point in time.
If you regularly have dozens or even hundreds of tabs open in Firefox, you may find useful what it brings to the table.
The add-ons main feature is the ability to close multiple tabs at once based on keywords you enter.
A keyword can be anything including words, domain names and even protocols.
The extension adds an icon to Firefox's toolbar that you click on when you want to use it. The form field is activated automatically so that you can start typing immediately. A tap on the enter-key in the end closes all matching sites in the browser.
Even better: this works across regular browser windows as well. If you have two browser windows open and type facebook, all instances of Facebook are closed from both.
It is usually better to type the full domain name and not use part of it only. If you type facebook and hit enter, all facebook.com pages are closed but also any other page that has facebook in its url. If you use facebook.com instead, only pages on that site are closed.
You can use the extension to close Firefox quickly by entering http in the Power Close form. This closes all http and https sites in the browser. As long as you don't have local pages or other protocols open, this should close the browser as all tabs are closed by the procedure.
The add-on could use a keyboard shortcut to use it even faster. Another useful option would be links in the tab context menu to close all tabs of the selected domain right away in Firefox.
Last but not least, a history of closed tabs would be useful as well as it would allow you to re-open tabs that were accidentally closed by the add-on.
Anyway, Power Close is a useful extension for Firefox users who work with lots of tabs in the browser occasionally or all the time.
