Doesn't work anymore, it lets you view but not edit anything. Hasn't been updated in 3 years either. Whether its the developer's fault, or Mozilla's fault, this app no longer functions for its intended purpose.

Ends up opening a bunch of useless popups that you don't have time to view before more are opened.

The name of this extension is a complete misnomer, one cannot actually tamper with the posted data, and since it claims to do what the old Tamper Data extension did, it seems intentionally misleading and borderline fraudulent. Do the right thing and change the name.

We can't edit data like the old Tamper Data...

Can't edit the request, so this addon doesn't make any sense.

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.

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.

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.
