disable paste context menus in firefox.

[abose]

Firefox does not support js initiated clipboard paste other than via extensions. Ctrl-c, Ctrl-V works though.

We should remove paste context menus from browsers that do not support navigator.clipboard functionality.

• [ ] Edit>paste menu
• [ ] document right click> paste @abose
