4chan X is a script that adds various features to anonymous imageboards. It was originally developed for 4chan but has no affiliation with it.
It was previously developed by aeosynth, Mayhem, ihavenoface, Zixaphir, Seaweed, and Spittie, with contributions from many others.
If you're looking for a maintained fork of OneeChan (a style script used in addition to 4chan X), try https://github.com/KevinParnell/OneeChan.
Uninstalling: 4chan X disables the native extension, so if you uninstall 4chan X, you'll need to re-enable it. To do this, click the [Settings] link in the top right corner, uncheck "Disable the native extension" in the panel that appears, and click the "Save Settings" button. If you don't see a "Save Settings" button, it may be being hidden by your ad blocker.
Private browsing: By default, 4chan X remembers your last read post in a thread and which posts were made by you, even if you are in private browsing / incognito mode. If you want to turn this off, uncheck the Remember Last Read Post and Remember Your Posts options in the settings panel. You can clear all 4chan browsing history saved by 4chan X by resetting your settings.
Use of the "Link Title" feature to fetch titles of Youtube links is subject to Youtube's Terms of Service and Privacy Policy. For more details on what information is sent to Youtube and other sites, and how to turn it off if you don't want the feature, see 4chan X's privacy documentation.
Install Violentmonkey, Tampermonkey, or Greasemonkey (issues since v4: #2526, #2576), then click here to install 4chan X.
Ports of Greasemonkey are available for SeaMonkey and Pale Moon.
Userscript: Install Violentmonkey or Tampermonkey, then click here to install 4chan X.
Chrome extension: 4chan X is also available as a standalone Chrome extension. The Chrome extension has the additional feature of being able to sync your settings and data with other devices via Chrome Sync. But there is an issue when the script updates: Whenever the Chrome extension is updated, until you hard refresh (F5) the tab, 4chan X is unable to save any data (such as posts marked as yours and settings changes). The userscript version above does not have this problem when 4chan X updates, only when Violentmonkey / Tampermonkey is updated. To install as a Chrome extension:
- Chromium, Vivaldi: Download 4chan X, then open
chrome://extensionsand drag the downloaded file onto the page. Alternatively, you can install 4chan X from the Chrome store. - Opera: Click to install 4chan X, then follow the prompts to activate it in your extension manager.
- Chrome: Install 4chan X from the Chrome store.
Note: This version of 4chan X does not work with Opera 12. If you need Opera 12 support, try loadletter's fork instead.
Install the Userscripts extension. Enable it by pressing ⌘,, navigating to the extensions pane and checking Userscripts checkbox. Now open the Userscripts editor by clicking on the </> button in the taskbar. Then click on the + button and select the New Javascript option. Replace the default text with the contents of the 4chan X script. Finally save it by pressing ⌘s.
Several minimal browsers have support for userscripts and can run 4chan X. Due to the lack of the cross-site GM_* API, and lack of support for userscripts in iframes, not all features will work. You may experience crashes when repeatedly solving the default image-based captchas. You can avoid this problem by enabling Use Recaptcha v1 in your settings.
