This extension makes web surfing much more comfortable for me. But there is only one issue which is a little bit annoying: if the Firefox find bar is open then the keyboard shortcut ALT+W is occupied by toggling the find option 'Whole Words" instead of closing other tabs. Thus it would be useful if there was an alternative keyboard shortcut for "Close Other" (e.g. Alt+Shift+F3) or even better if the keyboard shortcuts were configurable
