IncogPrio

A browser extension to mask student numbers and priorities in CRS, allowing you to conceal them in public (for privacy purposes).

Browser Support

• Chrome/Chromium (Chrome browsers)
• Firefox/Zen (Gecko browsers)

Installation

1. Install this Github repo

Chrome (Chromium browsers)

2. Go to chrome://extensions
3. Select Load unpacked and look for the chromium folder from this Github repo

Firefox (Gecko browsers)

2. Allow unsigned extensions by about:config -> xpinstall.signatures.required : false
3. Go to about:addons, click the "Settings" button (the gear symbol), and click Install add-on from file
4. Find and click incogprio.xpi from firefox folder

Installation done! Try it out in UPD CRS!

Potential Expansions

The extension is functional at best, but it can be improved with:

• not all student number instances are redacted as of now, only the ones in the sticky top bar, preenlistment, and home page.
• some fixes regarding validation (e.g. when no text is currently "saved" for priority, disallow checking).
• potentially generalize the student number redacting to any website.

I'll be quite busy since 2nd semester is starting though, so free to add a pull request!

Disclaimers

The effects are purely visual (for privacy purposes). This does not change your true priority.

Also, check your real prio from time to time by unmasking priority occasionally, just so you can check if it changed :D
