Recent reviews
This used to be a highly functional extension. It had a ton of features that I didn't care about, but the basics of it worked as intended. It no longer works. It adds a bunch of crap to the page that Dark Reader does not recognize, so instead of using my convenient dark mode extension I have to fiddle around with CSS to make 4chan look like i want it to. Quote threading being a default setting is absurd, and because there are like 200 options it takes forever to find even what this option is to disable it. Lastly, I literally could not even post with the extension installed because it did not display the captcha for me.
Bloated it so much you lost the absolute barebones functionality.

Is 4chan X Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
4chan X requires a few sensitive permissions. Exercise caution before installing.
