Firefox will block data uri to fight phishing

Browsers have taken the security of users very seriously. New measures are regularly introduced to guarantee it. Today is the turn of Firefox, which has announced that it will block URIs of browsing data. They do so as part of a campaign to fight phishing sites that use this protocol.

Firefox will block data URIs to fight phishing

The URI data schema allows the developer to load a file represented as an ASCII-encoded octet sequence into another document. This was introduced in 1998. Since then, the URI scheme has been very popular with website developers. It allows you to easily embed text or image files within HTML documents.

Firefox blocks URIs

It is a practice that has become commonplace in the industry. Although in the late 2000s it was observed that data URIs were beginning to be abused by phishing attacks. Something that has been refined over the years. Since then, phishing based on data URIs has been the most common. Something that happens every year frequently.

Google Chrome and Microsoft Edge were the first browsers to react and block data URIs within the navigation bar. Now, Firefox is the last browser to join this list. They seek to block high-level data URIs, which are the ones used mainly in phishing.

So with this decision, Firefox hopes to be able to introduce a notable security improvement for its users. Thus, reducing the possible phishing attacks that users suffer. What do you think of Firefox's decision?
