Building a UMatrix Replacement

For those not aware, the article assumes you are stuck in Google Chrome. Ublock works correctly in Firefox and derivatives, I advise you to use that instead to end the suffering.

If you find yourself in a "only Internet Explorer 5.5 is supported" situation, you could perhaps use Ungoogled Chromium and manually install Ublock Origin to buy yourself time to get out of that dead lock.

The "solution" is to not use Chrome anymore.

Firefox hasn't (yet) crippled their add-ons, and says they have no plans to do so (today).

NoScript can do what you want, and more.

Nice work! FWIW, you can still use Manifest V2 extensions, like uMatrix, uBlock Origin, or Violentmonkey, in Chrome by passing command line flags. For example, on macOS:

    open -b com.google.Chrome --new --args --disable-features=ExtensionManifestV2Unsupported,ExtensionManifestV2Disabled

When Google finally nerfs that, it is past time to move to Firefox or Brave, the latter of which has explicitly announced uMatrix support.

If you are running a modern Firefox, there’s still nuMatrix: <https://codeberg.org/arek/nuMatrix>

I still use umatrix

but cloudflare blocks my "outdated browser" all the time

Weirdly enough I was wondering what Tavis Ormandy has been up to recently, as I haven't seen his name associated with any global show-stopping vulnerabilities from the Project Zero team for a while.

I miss uMatrix, too. Thank you for working on this!

I don’t like Heroism, but finally a new article from Tavis Ormandy. Thanks for your work.

>I really don’t want to give that up – is there a solution?

Use Firefox, uBO works great. While I really enjoy seeing people find creative technical workarounds, the reason for it being needed in the first place is Googles fight against Adblockers with Manifest V3. Firefox allows people to sidestep this artificial downgrade of adblocking capabilities.
