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.

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.
