[Chrome] [ChromeOS] Does not install at all in ChromeOS s' latest builds.

[5dl0g1st1ca0]

I tried to reproduce the issue when...

• AdNauseam is the only extension
• AdNauseam uses default lists and settings
• Using a new, unmodified browser profile

Description

ChromeOS has removed the v2 manifest flag as well as the unexpire flags to re-enable those flags and now prevents AdNauseam from installing.

The advault json for it may be helpful, can we get it?

A summary of what i have tried so far:

Unfortunately disabling OS Verification leads to security compromises I'm not willing to take so dev mode is out.

I have tried cold adding different switches to the treat as secure origin flag box.

I have tried using crostini/aurora these cause other instability and security issues.

I have tried (multiple ways) (without any success) faking the min requirement/mv version info within the extension itself.

I have tried older versions of the extension and latest builds.

I have tried safety reset and then re-enabling the extension.

I have tried moving to beta as well as dev channels.

Has it lost any functionality ? Does it still keep stealth (clicking ads in the background) ?

it cannot be installed anymore

I was looking into possibly a way to get it installed using a buffer overflow because turning OSV off is like the last thing you want to do especially if you're using Gemini CLI or literally any higher Crostini functions. Also vivaldi and brave, etc etc are not options outside of Aurora because of browser artifacts and other even worse issues
