I just want to clarify since some people are confused(and I keep getting asked this like already 8 times this morning and I've only been up a couple hours)
CROPPY THE WEBSITE IS NOT DOWN.
only the bookmark extension for webtoon is down(Bookmark extension works like a charm for tapas)- most of you don't even use or know what that is, so if this is your first time hearing "bookmark extension" you can just go about your day as if nothing happened.
To those of you curious what the extension was: It was a bookmark you could load while on the upload page at webtoon, that modified the webtoon upload page to work the way you would want it to- allowing you to upload long files directly onto webtoon without getting a zip folder and all that jazz.
The extension still works for tapas, meaning you can use the bookmark while on your tapas upload page and it will slice your comic directly on site. By all means, go ahead and get the extension for tapas if you like.
