Run reviewed JavaScript tools and custom CSS on websites selected by you. CHC Injector is a rule-based workspace for applying packaged JavaScript tools and custom CSS to selected websites. Create rules for one domain, multiple domains, or all websites. Rules can run automatically or manually from the extension popup. Key features: • Domain-based injection rules • Automatic or manual execution • Custom CSS applied after synchronization • Packaged libraries including jQuery, JSZip and FileSaver • Account synchronization across extension installations • Review workflow for custom JavaScript • Permanent additional injection slots available through CHC Ideas For Manifest V3 compliance, custom JavaScript is not downloaded and executed remotely. Submitted JavaScript is reviewed and, when approved, included as a local file in a future published extension version. Users must update the extension before newly published JavaScript becomes available. CHC Injector is provided by CHC Ideas. Users are responsible for the code they submit and the websites where they choose to run it.
