2023-12-22 Firefox user 12604295 A tutorial would be helpful. I can't get it to add the desired query.

2023-10-07 Max Yudin The author aimed to create a progressive interface, but it turned out to be a flop. Also, after the last update of the plugin, it opens its settings tab every time I open Firefox. What I should do to prevent this from happening is not specified anywhere. Otherwise, the plugin does its job.
2023-10-03 Firefox user 16896802 Excelent to manage requests, creating controled data scenarios between user and server.
2023-09-11 Firefox user 18051580 useless. can't auto respond and modify request body.
2022-06-20 Firefox user 15797138 It works ok-ish. The interface could be somewhat clearer on when to save and how to enable. Also it seems like localhost throttling doesn't work. It does work when calling directly through deelay.me though.

2021-12-03 Andrea Pascal Is source code available for this addon? The license is listed as BSD 2-clause.
2021-12-02 Nishant Desai this extension is not working for me on locally hosted webapps, is that expected? I'm using a similar extension in Chromium and it works on localhost sites just fine. Any help is greatly appreciated.
