User reviews
Request Interceptor helps users manage and modify HTTP requests effectively for testing scenarios and URL redirection. However, multiple users report that the interface is not intuitive and lacks clear instructions, causing confusion about saving and enabling the add-on. It also has issues working with localhost sites, unlike similar tools on other browsers. Post-update behavior forces settings tabs to open every browser start. Overall, it performs its core function but could benefit from better UI, documentation, and expanded features.
Pros
- Effective in managing and modifying HTTP requests for testing and controlled data scenarios.
- Relatively easy to use once understood, helpful for testing feature behavior under different API responses.
- Supports redirecting and replacing parts of URLs with regex, offering flexibility.
- Performs adequately in general use as intended for intercepting requests.
Cons
- User interface is not very intuitive; saving changes and enabling the add-on are unclear to users.
- Lacks clear documentation or tutorials, leading to confusion about features and usage.
- Issues with localhost or locally hosted web applications not being supported or working properly.
- After updates, the add-on sometimes opens the settings tab every time Firefox launches, annoying users.
- Some desired features like auto-responding or modifying request bodies are missing or limited.
