User interface is mildly annoying. Every time I save a screenshot the add-on opens yet another instance of my system's (Xubuntu) file manager (in my case, Thunar). I'm amazed you managed to access the local filesystem from WebExtensions, though. How did you manage that? I can't find anything in the WebExtensions documentation that says that's supported. Is this add-on open source? I could use some file saving capabilities for my own add-ons.

so poor

no longer working

Won't allow selecting desired area AND scroll the page down to select more.

用这个功能主要是快速截图保存。作者可以去看下360或者QQ浏览器这个功能，好用很多。希望添加自定义快捷键方便快速截图保存

This add-on works incredibly well, but unfortunately I really hate the unnecessary sound effects, especially since I have very powerful computer speakers, and it sounds like I'm being fired on from outside with a gun every time I use it.

Is there any way to remove the sound effects or provide an option to disable them?

EXCELLENT

I never rate an extension but this one is really amazing

Interesting extension, unfortunately something must have been messed up with Firefox 80: no scroll down anymore.

Hope this can be fixed soon.
