SECOND NEW FEATURE REQUEST 9/12/2019:

Thanks again to the developer for implementing a new keyboard shortcut to trigger element blocking. If possible, I'd like to request another important feature. I'd like to be able to undo the previous block operation in order to restore page elements unintentionally zapped by said operation. Currently I see no way to do this other than unblocking ALL blocked items for the site and starting over, which is very tedious. An alternative remedy to an "undo" option might be to highlight blockable elements on mouseover to isolate precisely what content will be effected, thus mitigating the need for an undo option (though it would still not address accidental clicks).

--END OF SECOND NEW FEATURE REQUEST--

A very lightweight, sleek and swift content blocker, but like so many others there is no keyboard shortcut option to invoke the function. An ideal element blocker should require no more than one keystroke and one mouse click, but I have yet to encounter one. Best advantage this addon has over similar offerings is that this one remembers blocked items.

UPDATE: Great thanks to the developer for adding the keyboard shortcut option after only two days of leaving the review! This addon is now officially the least cumbersome and slickest element blocker there is for Firefox, and I've tried every one of them.
