The add-on would be great, if the shortcuts work properly. Unfortunately, they are either doesn't work at all or just working on add-on settings page. Sometimes they start working on another pages too, for a brief period of time, than stop. Something is broken there.

Please, fix it and it would be 5 stars! (or advise, what might be the problem). I've checked on two different computers with two different accounts - the issue is the same.

试用了一下，是在下载完图片之后才屏蔽的，流量已经使用了，另外视频试了一下斗鱼，实际上视频还是在下载，但只是页面上不显示罢了。

Works okay. Just shows content shortly sometimes before it hides it.

Good extension - crappy keyboard shortcuts.
This extension overrides the Firefox's default keyboard shortcut for tab navigation (Cmd/Ctrl+1, Cmd/Ctrl+2 etc)
Very very painful to use if you are used to using keyboard based navigation on Firefox.

[update 5-Apr-2018] Thank you for responding. May I suggest: A simple config option would be to completely disable the keyboard shortcuts - lest they conflict around with some users having custom shortcuts. Also blocking Audio when blocking the video is another thing worth 5 star review

Works as advertised, but it's a pain to have to navigate through layers of menu to turn it off and on.

Sometimes it loads images even though i blocked them!

Also an interface when clicking on the toolbar button would be more effective.
