Can't tamper the requests anymore. Pretty Useless. Is this a bad knockoff of tamperdata?

why we can't edit the request.

Well, despite the name you cannot tamper the *data* with this one. Sure enough, the description says what you *can* do and it does not mention tampering with (i.e. editing) the request body (i.e. data) only the headers but the name is 100% misleading.

Thanks for wasting my time.

If you want more than 1 star, then rename it to tamper request headers.

You can view requests, but cannot tamper with them, which is the opposite of the old "Tamperdata" and thus this is not the same thing at all.

why can not edit request parameter,modify the post data?

==Cons:==
As commented by other users before:
1. This extension cannot edit/tamper the request, that is **NOT** like the old "Tamper Data". The name and description are both misleading. Not sure if such kind of tampering is technically infeasible or just the author need more time to implement it.
2. The UI is awful and default window size when starting tamper exceeds my screen.

==Pros:==
Anyhow, this extension still can list all the parameters of the HTTP header, which provides a easy way to analyze your HTTP/HTTPS requests, especially for HTTPS, comparing to other approaches. That's why I give one more star.

it's crap

Bad bad naming. This does not "tamp" anything... and the UI is awful! Do not install this...

I am unable to even process how does this work at all. It did not help in what I needed it for. It doesn't look like anything like the old Tamper Data extension, thus making it extremely difficult to even understand how this "new" version works.

Unfortunately, it indeed does not allow editing requests.

The description is "It's like the old Tamper Data extension, except it works on modern versions of Firefox." but it doesn't let you 'Tamper Data' like the old addon did. The developer has said on github it's not supposed to let you modify post data but is using the name tamper data even though it is missing one of the major use cases. It's misleading and bad form.
