Right-click contenteditable is a free Chrome extension developed by Paulius Sasnauskas. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory.

This extension allows users to easily add or remove the contenteditable attribute to elements on a webpage by simply right-clicking on them. By selecting the "Add contenteditable" option from the right-click menu, the targeted element will be given the contenteditable attribute, allowing the user to freely edit its content. To remove this attribute, the user can simply click the button again.

Right-click contenteditable is a useful tool for editing typos in text, especially when multiple readings are required. Additionally, it can be used to create entertaining screenshots of web pages where the text should be different from what was originally typed.

For more information about the contenteditable attribute, refer to the Mozilla Developer Network documentation.
