Firefox will offer an option to check if our browser installation has been compromised

mozilla firefox

Mozilla is working on a new security feature that perhaps should be standard on all open browsers. This is a project called Binary Transparency, its purpose is to allow third parties to verify that all binaries in Firefox are public, that is, they have the same version as the rest of the world and not any special and possibly compromised version.

The binaries of an application are the executable files or the updates produced when building the program. As Firefox is an open project, anyone can build their version of the browser using the source code, so there are so many browsers based on it. Unfortunately not all those versions have good intentions and Mozilla wants to make sure it provides the tools to prevent malware.

Most users just download compiled versions of the browser from the Mozilla website or from another site, and when it is already installed we use the same browser to update automatically.

The binaries of Firefox do not come with any assurance that they correspond to the same source code of that version of Firefox, and although it can be reviewed comparing the source code, in reality this is not something that everyone does.

This is where Binary Transparency comes in. The main idea is to add all the binaries of Firefox to a public file that anyone can review and compare the local binaries of your Firefox installation to verify that they are the same that everyone uses and it has not been modified.

In addition to this, Mozilla also plans to integrate the feature into the same Firefox updater, so that any updates are verified before being downloaded and installed on your system.
