User Reviews

Users appreciate 4chan X for its convenience features, ease of use, and customization options when browsing 4chan-type sites. However, many report that the Mozilla version is outdated, leading to broken captchas and incompatibility with certain boards like 4channel.org. Concerns about required Google access permissions are noted, and uninstalling the add-on may cause further issues. The consensus is to download 4chan X directly from its official website for better updates and stability.
Pros
  • Adds many convenience and customization features for browsing 4chan-type sites.
  • Easy to use with default settings that work well for most users.
  • Can update itself automatically when obtained from the official website.
  • Works well on some NSFW boards when functioning properly.
Cons
  • The version available on Mozilla is outdated and may not work correctly.
  • Captchas are broken or cause issues, requiring access to Google data, which concerns some users.
  • Does not work properly on 4channel.org domains or blue boards.
  • Uninstalling can worsen site functionality or cause broken features.
  • Some users recommend obtaining the add-on from the official 4chan-x.net website for latest updates and functionality.

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.
