Create and use scriptlets

[fabriziobagala]

Hi everyone, these days the Brave browser has released a feature that I have been looking for a long time and I find great, namely the ability to create and use custom scriptlets. Would it be possible to implement something similar in Firefox? Thank you.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

Run userscripts (on one or tabs) with a manual user action

@Anonymous are interesting extensions but I would prefer to use something built-in to Firefox, as Brave has done.

Firefox doesn’t currently support custom scriptlets like Brave does. You can get similar functionality using extensions such as Tampermonkey or Greasemonkey, which let you run your own user scripts on websites. It’s not built-in, but it works as a good alternative for now.

It would be great if Firefox could implement a similar capability, enabling advanced users to define and apply custom scriptlets directly within the browser or through built-in tools. web

Nice idea. Brave can do this because scriptlets are built into its ad-blocking system. Firefox usually leaves this kind of power to extensions like uBlock Origin or Tampermonkey, mainly for security and maintenance reasons.

If there’s enough community demand, Mozilla might consider native support, but right now extensions are the intended path.

Same logic applies elsewhere: reusable, modular tools scale better than hardcoded features. A short-code-generator follows that idea by keeping things flexible and clean
