User reviews

Users appreciate the extension for its ability to inject CSS and JS directly and efficiently, boosting development workflow with a simple interface. Key drawbacks include that it applies changes only to specific page URLs rather than whole domains, often requiring page reloads to see updates. Some users report saving issues and lack of advanced code editing features, as well as occasional bugs like automatic unchecking of domain-wide application. Overall, it is valuable for targeted page customizations but could improve global application and live reloading.
Pros
  • Real-time CSS and JS injection on pages streamlines development and improves productivity.
  • User-friendly interface with a simple and effective code editor for customizing pages.
  • Works well for modifying individual pages and is especially useful for developers needing quick style changes.
  • Injects code directly into page HTML, allowing interaction with page variables not accessible by other tools.
  • Saves time and supports persistent style changes without affecting iframes.
Cons
  • Injection is limited to exact page URLs rather than entire domains, which reduces flexibility.
  • Changes often require page reloads to take effect; live reload or real-time preview is inconsistent or missing.
  • Does not always correctly save CSS or JS edits, causing users to lose work or have to refresh repeatedly.
  • Injected styles are sometimes overridden by page styles requiring !important, and the extension does not support advanced editing features like autocomplete, linting, or prettifying.
  • Apply to domain option can uncheck itself unpredictably, and performance issues such as errors in logs have been reported.

It will only affect the exact link, makes it rather useless. Should be able to cover a complete domain

5 stars because it has potential. It has an issue though : It will only affect the exact link For example customize `example/random` then go to `example/` it won't work, would work on dynamically loaded pages like discord for example (though I haven't tested) Managed to find a different extension that does it globally, but it could be nice to have a select dropdown for local/global or something similar! Hopefully this extension can improve from this review
