Fools shouldn't use addons.
You didn't write a specific page in your first comment. There is no way to find out anything just by writing that it doesn't work. So fools shouldn't use addons. You say another add-on doesn't work, but this add-on and similar add-ons change the content of the page when it's running so that you can right-click on the page, so of course that can happen. . The primary purpose of this add-on is to be able to do that on pages that block right-click and copy, so I won't consider anything else. You only need to enable this add-on when you want to right-click and disable it when you are done right-clicking. You probably don't even understand that the addon's description says that this addon doesn't work on all sites. If it doesn't work on a page, use another similar add-on on that page. It shouldn't matter if you have multiple add-ons installed, as long as you don't use them at the same time. As noted in the description, sites block right-clicking in a variety of ways, so there's no one-size-fits-all way to enable right-clicking. Pages that don't work with that addon may work with this addon. I'm updating this addon for that. I don't care if it works on the pages you want to use. Just make it right-clickable on the pages I want to be right-clickable. You're neither a stake holder nor a paying customer, you're just using someone else's software for free. So I'm not going to make what you want. If you want the software you want, you should build it yourself or hire a software developer to build it.
