  • Worked like a charm first time. Concise documentation. Simple job, but done very well. thank you
  • Ready to operate in a few seconds. Just have to add it in the toolbar after downloading. Really usefull.
  • I had a trouble with cors all day and finally it worked. Thanks for this helpful add-on.
  • As a web developer, this add-on is a life (and hair) saver for when you don't have access to the server. Works as intended.
  • Hi it's works really great. Thank you

    I just have one plea, please could explain or paste links, how to create CROS request. I couldn't find any SIMPLE references, because I have error("Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://www ... html. (Reason: CORS header 'Access-Control-Allow-Origin' missing).").

    They all just telling to add header "Access-Control-Allow-Origin", but how and where. Thanks for advance.

    I already read the most Google links, including on html5rocks (where example throws the same error). But it does not work for me.

    P.S. By using you addon it works
  • Hi, that works great!

    Could you clarify how to set it enabled by default?

    Where do i set `extensions.spenibus_corsEverywhere` enableAtStartup?

    Thanks

  • It does not seem to work on Mac - 45.0.2 release.
  • Установил этот плагин и ни какой реакции, кнопка CORS не появляется в браузере.
    При попытке сделать кроссдоменный запрос, консоль выдает следующие :

    Запрос из постороннего источника заблокирован: Политика одного источника запрещает чтение удаленного ресурса на http://localhost:8080/opt/in?&1450674147940. (Причина: отсутствует заголовок CORS 'Access-Control-Allow-Origin').

    P.S.

    С бубеном ходил вокруг компа в разные стороны, не помогло.

    Developer response

    Based on a rough Google translation, I can only point out that the button is not automatically added to the interface and must be placed manually by right clicking a toolbar and selecting "customise".

    Without the button, the addon can not be enabled and obviously won't work.
