Downside - It disables dragging. For example, Amazon.com with this addon, you cannot move your shopping lists sort order. Also, in TEXT boxes that allow you to resize the text box from the bottom right doesn't work. If you cannot fix this, then you should allow user to put it on the tool bar and disable it for certain websites, or at the very least, allow it on the tool bar and allow me to click on/off the addon without having to go into the addon menu and disable it.

Thank you for your contribution, it does work as intended on a few sites that refuse to allow me to paste.

As for another user claiming Happy Right Click works, For a banking site, Your addon works at allowing me to paste, while Happy Right Click does NOT. So, your addon has value to me.

worked for me to bypass not being able to copy on an e-book website

Right click works, but breaks dragging/scrolling e.g., on maps

Causa problema em alguns sites desativando recursos que não tem relação alguma com o click com botão direito do mouse e demorei para identificar que a causa era essa extensão. Passei a usar a Happy Righ-Click e até o momento não tive problema.

会导致所有的进度条及需要拖拽滑动的东西都无法正常使用

非常好用，原先有些网站不让复制的文字，也可以直接复制了.
但是目前发现，开启它，有些网站视频的播放进度条就无法拉动了，比如b站。
