感谢分享.

good and useful, thanks!

Edit: Its working now. Content-Type header was missing, tho it worked fine with curl
POST request aint sending any data, the post object is empty. Im using codeigniter 3 with php 5.6 running on a local (127.0.0.1) xampp 5.6.11 server. Old extension worked just right.

This application does not work. It just hangs for ever. The old application (1 year ago worked fine) This oneshould be modified to return an error. Also a short document should be given so as to know if specific Firefoxe parameters are needed
Cette extension ne semble pas fonctionner. J'envoie une requête GET l'application semble s'exécuter mais la page est bloquée pour toujours sans aucun message d'erreur ni rien.
L'application devrait être revue de manière à fournir un message d'erreur mais non à bloquer définitivement.

Nice addon, but I have met troubles with encoding of Cyrillic.

... now I even cannot read anything in the UI anymore, font size by far too small and in addition a very thin one without any contrast which renders the tool totally useless. Also cannot use favorites anymore, even though not being in private mode.

firefox 51 64位版本，使用RestClient2.0.1，自动升级到3.0.5后，以前保存的Request很多，按提示在migrate面板复制三项数据
extension.restclient.cachedUrls
extension.restclient.favoriteHeaders
extension.restclient.savedRequest
然后点击"migrate it now "，没有任何反应。试了二十次，最终放弃了，还是用httpRequest

简单，好用

之前用过还可以，但是最近用的时候为啥点击那个headers内的custom header怎么点都无反应，无法配置header
