Update 02/04/25: This doesn't seem to be an issue anymore. Also, the recent addition of the fill button is a huge improvement for editing an item without having to search for it like it was previously.

Used to be great, the service itself is amazing. But recently (months ago) there's been a bug every time I try to open it on a private window. It just shows a white square where the addon popup should be and I can't access the internet on any firefox window until I close firefox completely.
