Dear Vinay Kumar, I am struggling to use this extension to intercept and modify a web request. There's nothing that I can refer to as a guidance or demo. Kindly share its SOP or something by which all of the users can have benefits of this tool without hurdles. Thank you.
Great, Free, comprehensive function. :D
Hey @vinaykumar, Great extension. We have a use case where we need to intercept some network requests and add query params on our website. Can you let us know how to achieve that? Any disclosure about the source code?
looks great but can i edit resp body?
It will be more useful if supports modifying "request payload" and "response".
Works nice to replace static assets!!
It's good, but most of people are thinking it's not working because it's completely off by default (with the top right button).
useless, as I can't modify response!
No documentation on how the tool works as well as simple rules doesn't take effect. Has no effect on the sites. Feels like a data mining extention as all it want access to is your browser history and does nothing with it.
Cool extension. Is it possible to intercept into the response body and add functions such as export to json files or excel files etc.? Thanks.
