Why am I seeing injected ads?

Some extensions show ads or modify pages. If you see unexpected ads, switch to a privacy‑first alternative that does not inject content.

Is there a safe alternative?

Yes. VibeHeader is an ad-free, MIT-licensed Manifest V3 request-header editor. Profiles and Request Filters are stored locally, and shared setups can be reviewed before import.

How do I switch quickly?

Install VibeHeader, create a Profile, copy the compatible request-header names and values, rebuild the URL scope with Request Filters, and verify the result in DevTools.
