Legit one of the most underrated Firefox features that I use all the time: right-click -> Take Screenshot (or Ctrl+Shift+S). No need to look up the relevant node, just hover the relevant part with your cursor.
That doesn't align itself to the dimensions of an element. The screenshot thingy even allows you to screenshot past the visible area for scrollable pages
It wouldn't improve anything about the resolution or quality of the image you'd just get slightly more of the image. Seems like it would be useful in niche situations though.
Eh. I like imgflip a lot and their watermark is super unintrusive, so I leave it to support them. If it was a worse watermark I'd feel no qualms about going around it but it's small enough that I feel happy including it.
imgflip devs should've known better. Just adding a img element on another img element won't do. You gotta generate them together and add only one img element where the watermark is edited into the image.
Too lazy to generate the appropriate image (with or without watermark) depending on users subscription status on the server side ig.
It looks like the image is processed in the server-side. The page sends a POST request with a bunch of x and y parameters about text boxes and custom images.
