I am always glad to see new Firefox forks, but some things look unfinished. For example, Google search and shortcuts on the home page are not cut out.

Thorium has a history of being bundled with Yiff (furry porn) withing the program structure folders, while some other users report their antivirus detect a Troyan file bundled with it.

It's appreciated people get involved on developing forks, but is hard to trust when your initial public projects are bundled as mentioned. Not a great start to getting recognised as a developer of trust.

As the Guest user said; Mercury Browser is one of some projects such as Thorium, both developed by Alex313031.

Alex313031 has previously shipped Thorium with an "easter-egg" which contained a "yiff" image, completely unprofesional behaviour at the expense of his trust once users discovered.

Some other users had received anti-virus warnings about a Troyan being bundled on Thorium, even one user stated to have found a dataminer at the password's save-forms.

Alex313031 has acknowledge his mistakes, but at first place there was never a reason to bundle such image on the browser, making irreparable trust damage to his contributions.

It may be up to you to decide to give his projects a chance. But his software are never touching my OS nor Computer. Maybe under a VM for testing purposes? Who knows, too risky.

What is Mercury Browser?

Firefox fork with compiler optimizations and patches from Librewolf, Waterfox, and GNU IceCat. It aims to be the Firefox equivalent of my main project: Thorium (a Chromium fork).

  • Compiler optimizations include AVX, AES, LTO and PGO.
  • Learn more about these compiler optimizations and how they work Here.
  • Patches and UI changes that enhance useability, and strengthen privacy/security.
  • Many of these come from LibreWolf, Waterfox, FireDragon, PlasmaFox, and Ghostery.
