The solution on linux should be to install system-wide "policy" extensions - they support webRequestBlocking. Possibly via system package manager.

How would one go about doing this?

For UBO, first they'd need to implement MV3 while still keeping webRequestBlocking.. it seems that there's currently no information about this, so I asked them: https://github.com/uBlockOrigin/uBlock-issues/discussions/35...

In general it involves setting ExtensionInstallForcelist, but I haven't tried it in practice yet, it's a concept..
