huuduy216 I've released a new version (3.8.0) that should work with alternative text editors.
Unfortunately, there's an incompatibility with the paste to upload feature I'm unable to resolve, so it's now an opt-in feature which can be enabled in the extension settings. The problem is that in the rich text editor if you paste an image it will be added inline by the editor, but it would also be uploaded to Imgur at the same time, and I don't know if there's a way to disable that behaviour.
