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!

really needs to work better in Firefox for Android. refuses to remove the "open in app" floating button or floating Whatsapp icon from at least Times of India.

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

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.

Excellent, does what it promise but, sadly, only on desktop. Can you make it work in Firefox for Android on a mobile? I use Nightly with a custom addon collection, and the problem is that it doesn't seem to have a toolbar, so I cannot tap the icon or press the keyboard shortcut, this being a phone.

Works like a charm!
