Improved Intra 42

A browser extension which adds many improvements to 42's Intranet at, such as a dark theme and links to clusters when a user is available.

Quick Download

Google Chrome Mozilla Firefox Google Chrome (macOS User Profile Script)

A small list of features added by this extension:

  • Dark Theme! Finally, your eyes can rest when working at night.
  • Customizable user profiles! Now you can show a bit of your personality through your user page: add a custom banner image to your profile, visible to everyone with the extension installed, or add a link to your GitHub-page.
  • An option to use the old Black Hole countdown instead of showing one's absorption date.
  • Removal of the broadcasts button, which is unused by most campuses.
  • Replacement of the Black Hole for Codam students, simply showing the progress towards their monitoring system instead.

You can find the full list of features in the Wiki.


Available on the Chrome Web Store. If you are using a Mac at Codam, you'll find that any extensions you install often get removed after logging out. I wrote a small script for this, which fixes this issue by forcefully installing the extension to your macOS profile. You can find this script here.

For Firefox, please see the Releases page. Mozilla has decided to no longer host this extension due to it being for a "limited/non-public audience" (your loss, Mozilla). The extension should still automatically update using GitHub.


If you wish to contribute to this extension, please follow the contributing guidelines in the Wiki.

    Other git hosting platform link

    I think it could be pretty cool if we could add our username on other git-based hosting platform (especially self-hosted one). A few exemple would be gitea, sourcehut or gogs, to name only a few.

    Added Kleine speler post-fix title for Xander Voorvaart

    Everybody knows Xander loves calling people a 'Kleine speler'. The best way to get back at him, is obviously to give him a little taste of his own medicine!

    Custom color scheme

    Having the ability to input a custom color for the color scheme could be interesting. So if for some reason people want a different shade of blue, of red, or just want a different color all together, it's possible to change it.

    Sort projects on user profiles by project name instead of their slug

    Is your feature request related to a problem? Please describe. When you visit a user's profile on Intra and look at the projects a user has completed, these projects are sorted by slug (URL path) instead of by their name.

    Describe the solution you'd like Using Javascript, it might be possible to sort the projects based on their names instead.

    Change first day of the week of the log time calendar.

    Request: Represent the log time calendar with Monday as first day of the week.

    This could be archived by rearranging the rectangles of the calendar SVG element, by manipulating their x and y values. This feature should probably be a setting, to make the change optional.

    Additional notes: Since in some areas in the world, the first day of the week is Saturday, a third option or a free selection for day could also be an option (but might be more complex). The default setting could be set depending on the user's locale.

    (PS : I'm not very smart so maybe so it's caused by something I've got (for example i have the Dark Reader extension but it's deactivate on the intra so i don't know)) (PS1 : I'm french don't judge my writing)
