Features & Capabilities

Scratchpad is a powerful Firefox extension designed to replace the JavaScript Scratchpad editor removed in Firefox 72. It provides an interactive environment where users can write and run JavaScript code directly within Firefox. Accessible via the browser's Tools menu, Scratchpad opens one or more windows that allow code execution in multiple contexts — including the active tab's page context, Scratchpad's content context, or background context. This flexibility enables developers to experiment and test JavaScript seamlessly within Firefox.

Built with CodeMirror 5, Scratchpad features a robust and user-friendly editor interface under the MIT License. It is an excellent tool for developers seeking to code, test, and debug JavaScript quickly without leaving their browser.

User Reviews

Good but please add tab support, having only 1 script 1 painful for multitasking

Thank you so much for that extension! Scratchpad was one of those features which made Firefox special and I seriously missed it once it was gone. I hope one day mozilla will stop trying to imitate chrome and gets back to what really matters: security, user convenience and outstanding features!

Is Scratchpad Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Scratchpad requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Scratchpad has earned a fairly good reputation and likely can be trusted.
