Reviews of Referer Modifier

Referer Modifier is generally reliable and useful for controlling the referer header to bypass server blocks (e.g., 403). Users report it runs in the background for years and works well across privacy-conscious Firefox setups, including different browsers like Waterfox. It’s particularly helpful for sites like Pixiv that depend on referer checks, and it can save developers time by avoiding custom code. Some users note the UI is not polished and that the add-on could benefit from a dedicated settings panel, but overall it delivers practical referer control.
