Focus keyboard is an Firefox Addon which adds keyboard enhancements to improve your browsing experience.It takes care of all those steps that we take to open websites, edit URL in address bar, copy the URL from within the webpage to address bar, etc., and replace them with overly simple ones. For example, with this addon, you don’t need to highlight the URL in address bar to edit it or enter new web address, just start typing the web address you wish to visit and it will automatically start entering URL in address bar. Similarly, you can use Enter key to reload the page and Delete key to quickly jump to the end of URL address to edit it. It also allows adding URLs in Ignore list to let you browse through defined websites without these functions being enabled.
Main features section, you will find options to Automatically type in location bar Tab in order between checked elements, and to Highlight tabbed element.Additional Keyboard Enhancements section you can set/reset Escape blurs focus from any element including the location bar, Enter reloads the current page,Delete jumps to the end of the location bar's text, CTRL+V automatically pastes into the location bar or the search bar.
Black List tab: This allows you to disable Focus keyboard on a particular URl. Just add complete url of the page you want to blacklist.
