Browser extensions

This article explains with a few examples how you can configure browser extensions (add-ons) that protect you from ads, trackers, and similar website content – so that mailbox works without problems.

Allowing JavaScript with NoScript

NoScript is an open source add-on for Mozilla Firefox that gives you detailed control over JavaScript execution and provides additional security features such as protection against XSS attacks, web bugs, and click-hijacking.

We strongly recommend that Mozilla Firefox users install the NoScript add-on.

To use the websites of mailbox and the web portal in full, you must allow JavaScript for the domain pattern *.mailbox.org.

Allowing cookies

For registering an account, using the mailbox Suite, and logging into the forum, cookies must be enabled.

Please configure the settings in your preferred cookie management tool accordingly. If you generally block cookies, you need to add an exception for https://mailbox.org.

The following configuration is required for Mozilla Firefox:

1. Go to Settings > Privacy & Security > Cookies and Site Data > Manage Exceptions.
2. Add https://mailbox.org as an allowed exception.

Optionally, privacy tools such as Cookie AutoDelete can help you allow mailbox while still automatically deleting unnecessary cookies from other domains.

Ad blockers

mailbox does not display advertising and does not use tracking scripts.

We nevertheless recommend that you disable ad blockers completely, at least for the domain app.mailbox.org, to avoid problems with incorrect display or missing elements.

Some ad blockers interfere significantly with the display of web pages and cause damage to them, meaning that functional elements in the mailbox Suite may not be displayed, the layout may be incorrect, or errors may occur that are difficult to reproduce.

Furthermore, ad blockers can prevent the download of fonts that are necessary for the pages to display correctly. You may then see only unreadable symbols instead of icons on the mailbox Suite.

To enable the required features for app.mailbox.org, where they are actually needed, use uBlock Origin, an open source ad blocker.

1. Enable external fonts in uBlock Origin.
2. Save this setting by clicking on the padlock icon.
3. Reload the page.

Canvas Blocker

The add-on CanvasBlocker is open source and can block or restrict access to the canvas API, preventing fingerprinting techniques.

However, the canvas API is required in mailbox Suite for word processing, spreadsheets, and presentation mode. The login process also checks for its availability. You should therefore set up an exception for mailbox in your rules.

Add app.mailbox.org to the CanvasBlocker whitelist. This way, the add-on does not need to be disabled, and you can use mailbox Suite without restrictions.
