I use this extension to remove sign-in elements on businesses' Facebook pages which I otherwise can't remove since I don't have a Facebook account. It achieves this task well. Simply press the extension's control button to activate, hover over the element to select it, click to remove it, then press the extension's control button again to deactivate: very simple! Also reassuring that no special permissions are required, since manual activation of the extension is required each time you wish to use it.

This tool replaced the similar option I had with the FireGestures add-on. It's very convenient and useful. For me, this is one of the most important add-ons for FF. Thank you Sevina!

Exactly what I needed! I use this in conjunction with uBlock Origins static filters.

I've been using Firefox since it was called Netscape. Probably used hundreds of addons (I have 48 active at the moment). This one is absolutely THE MOST USEFUL addon ever. Congratulations to Sevina.
A suggestion: Reverse Mode. Select what you want to keep, click: everything else is removed.

Works great. I can't live without it!. So many websites have distracting, screen-space-wasting floaters. I have used this extension for a year or so.
