It's a good idea, but it sometimes leaves artifacts behind and sometimes (rarely) does almost nothing at all. Shortcut is nice.

Doesn't work on reddit.

стильно выглядит, приятно пользоваться

Useful, but on website pages that have 'click more to read/view' buttons at the bottom of an article, those dont work so you might not be able to access all of an article. Example a new website article with a gallery which has a click to view more images button, that wont work nor do any other buttons on the website page whilst this is running.
I would submit this to a feedback, but i dont use twitter.

good!

Helps not always, but quite often to remove a lot of annoying floating foregrounds of all kinds.

Works like magic!

Great idea. But I tried many sites, and this add-on was never able to remove one single pop-up. Ctrl-Shift-X had no effect whatsoever.
